Sandstone Conservation in Chinook Country

Written by: Fraser Shaw, Heritage Conservation Advisor

Paskapoo sandstone has been maligned for poor durability, compared to Indiana limestone and sandstones from Ohio or Spain that have been used for conservation projects in Alberta. But to be fair to our homegrown sandstone, masonry in general suffers in Alberta’s climate and in the intense sunlight, drying winds and freeze-thaw cycling in areas like southern Alberta. De-icing salts used for public safety during the long winter months are the nemesis of historic masonry and will relentlessly attack sandstone, limestone and granite alike. How stone is laid in a wall, masonry mortar composition, and design details all contribute to how stone performs over time.

An imposing landmark in downtown Lethbridge, Southminster United Church is a large 1913 building (additions in 1914 and 1950) with a bold Modernist 1961 chapel. The Classical Revival original building dominates with its symmetrical front facade, prominent pediment, monumental engaged columns and exterior of buff-coloured brick with sandstone details. Interestingly, while stone decoration of the 1950 north addition superficially resembles the regional sandstone, it is actually imported Indiana limestone, a different and relatively durable material. Other notable Lethbridge buildings with this combination of local and imported stone are the Galt Museum (former Galt Hospital) and the Bowman Arts Centre (Manual Training School), both Provincial Historic Resources. Lethbridge designated Southminster United Church as a Municipal Historic Resource in 2016.

A cherished High River landmark reemerges

Written by: Fraser Shaw, Heritage Conservation Advisor

Recently, I visited the Maccoy Homestead in High River after seven long years of flood repairs and conservation. Nestled in Sheppard Family Park near the south edge of High River, this was the farm and home of well-known local resident Ruth Maccoy for over 70 years. Upon her passing in 1995 and at her bequest, the farm became Sheppard Family Park with the homestead as its nucleus.

The home is a charming 1883 whitewashed log building, the earliest structure on the site, with a frame addition and porch built by her parents in the 1920s and surrounded by a garden and picket fence lovingly tended by Ruth Maccoy over the years. Behind the house are a garden shed, a small guesthouse, and a root cellar set into an embankment, while the garage is located nearby. A path leads west through the trees to a footbridge over the Little Bow River, usually a shallow creek, to the historic water source in a natural spring.

One of High River’s first municipal designations, the Sheppard/Maccoy House was designated as a Municipal Historic Resource in 2009 by the Town of High River for its association with Ruth Maccoy and early settlement in the area. An exceptional example of an early farm, the site also exemplifies the contribution of women’s labour to homesteading and agriculture in rural Alberta and was designated a Provincial Historic Resource in 2015. The site is a good example of how complementary municipal and provincial heritage values tell a richer story and was the subject of a RETROactive post earlier this summer.

Municipal Historic Resource designation refresher series: Provincial Historic Resources and Municipal Historic Resources

Editor’s note: Welcome to the final post in a series of blog posts developed with municipalities in mind who either have or are considering undertaking Municipal Historic Resource designation. In this post, we will discuss how the evaluation of a historic resource at the provincial and municipal level may result in complimentary or differing heritage values. You can read the previous post here.

For more information, please review the “Creating a Future” manuals available here or contact Rebecca Goodenough, Manager, Historic Places Research and Designation at rebecca.goodenough@gov.ab.ca or 780-431-2309.

Complementary and differing values

Alberta’s Historical Resources Act empowers both the Government of Alberta and municipalities to designate, or recognize and protect, a range of historic resources whose preservation is in the public interest. These resources can be places, structures or objects that may be works of nature or people (or both) that are of palaeontological, archaeological, prehistoric, historic, cultural, natural, scientific or aesthetic interest. Albertans value these historic resources because our past, in its many forms, is part of who we are as a society and helps give our present significance and purpose.

As of July 2020, there are currently 390 Provincial Historic Resources (PHR) and 413 Municipal Historic Resources (MHR) in Alberta, some 60 of which are designated both provincially and municipally. These resources merit designation for various reasons, from their association with significant events, activities, people or institutions; as representative examples of architectural styles or construction methods; for their symbolic and landmark value; or their potential to yield information of scientific value.

Heritage values are described in short Statements of Significance, which are listed on the Alberta Register of Historic Places. In this post, we look at examples of heritage values that municipal and provincial governments recognize and how local and provincial values may align, differ or complement each other.

Plaques or markers are often used to identify designated historic resources. These plaques, affixed to Strathcona Public Library in Edmonton, show that it has been designated as a Provincial Historic Resource and a Municipal Historic Resource. PHRs are identified by a blue, enamel button or marker. MHRs can be identified by a variety of plaques and markers depending on the procedures of the municipality.

Revival of a Prohibition-Era Landmark in the Crowsnest Pass

Editor’s note: You can read more of Fraser Shaw’s series on heritage conservation on RETROactive.

Written by: Fraser Shaw, Heritage Conservation Advisor

Gunshots shattered the stillness of 18 Avenue in Coleman on the afternoon of September 21, 1922.

Local bootlegger Emilio Picariello and his accomplice Florence Lassandro sped off in a cloud of dust as Constable Stephen Lawson lay dead outside the Alberta Provincial Police barracks, a cottage-like office and residence where he worked and resided with his family. Hours later, “Emperor Pic”—as he was known locally—and Lassandro were apprehended and charged with Lawson’s murder. Both were later convicted and hanged. Lassandro became the first woman to be executed in Canada since 1899 and the only woman to be hanged in Alberta.

The Alberta Provincial Police (APP) Building, a Provincial Historic Resource within the Coleman National Historic Site, is significant for its association with the infamous murder of Constable Lawson and, more generally, with its role in the maintenance of law and order in the mining communities of the Crowsnest Pass during Prohibition until the 1930s.

Restoration of the Taber Courthouse

Editor’s note: If you’re interested in other restoration projects by the government’s Heritage Conservation Advisers, read about the conservation of Circle L Ranch.

Written by: Fraser Shaw, Heritage Conservation Adviser

Designated a Provincial Historic Resource in 2013, the Taber Courthouse presides over a quiet park just off Taber’s main street. The building’s stately arched entryway speaks to its historic importance as one of Alberta’s first “sub-jurisdiction” courthouses, a system of provincial justice administration introduced at the time.

Built in 1918, Assistant Provincial Architect J.B. Allan developed the courthouse design and noted Provincial Architect Richard P. Blakey subsequently revised it. Blakey’s eclectic mix of Edwardian, Classical Revival and Spanish Colonial Revival elements eventually became an architectural prototype for other courthouses of the period. Examples of Blakey’s work that are still intact include the Blairmore Courthouse in the Crowsnest Pass and the Medicine Hat Courthouse. Both of these buildings are Provincial Historic Resources.

The conservation of Circle L Ranch

Written by: Fraser Shaw, Heritage Conservation Advisor

If you’ve ever driven down the beautiful Cowboy Trail, chances are you’ve driven by at least a few historic ranches. Some of these ranches, like Bar U and E.P., have been operating for over a hundred years.

Another of those ranches is the Circle L Ranch, started by a storekeeper from Salt Lake City in the late 1800s. The site recently underwent a restoration project to help ensure historic small-scale ranching in remained intact and accessible. The ranch is a Provincial Historic Resource and an excellent example of an early family-run ranch in southern Alberta.

A New Roof for St. Ambrose Church

Located on a quiet residential street in Redcliff, Alberta, St. Ambrose Anglican Church is distinguished by its buttressed brick masonry exterior, steeply-pitched gable roof and pointed arch windows. These characteristics strongly identify the 1914 church with the Gothic Revival style popular in the Victorian era for ecclesiastical architecture in England, a style also eagerly adopted by Anglican, Presbyterian, Methodist and Congregational churches across Canada. Unlike many churches, though, St. Ambrose was modelled on small Anglican parish churches in England and is a variant of the Gothic Revival style seldom found in Alberta.

St. Ambrose’s architecture hearkens back to England but the building’s local roots are evident in the “clinker brick” masonry exterior, an overfired brick with distinctive irregular or lumpy shapes and striking colour variations. Clinker brick resulted from high firing temperatures in the kiln which caused the clay to partly vitrify or melt, sometimes to the point where clumps of bricks would fuse together and had to be broken apart. This lack of uniformity was appreciated for its decorative qualities and the clinker brick at St. Ambrose was produced at the Redcliff Brick and Coal Company just blocks away. The combination of far-reaching colonial stylistic influences and distinctive local materials contributed to the church’s designation as a Provincial Historic Resource in 2008.

Dealing with Graffiti at Historic Places

Historic places are unfortunately fair game for graffiti attacks – sometimes especially so when these places are visible and widely recognized landmarks. Defined as writing or drawings scribbled, scratched, or painted illicitly onto walls and other surfaces, graffiti from a heritage conservation perspective is an intervention to be removed or reversed. It clearly differs from old markings that are an acknowledged and legitimate part, or “character-defining element”, of a historic place. Examples of the latter are prisoners’ inscriptions etched into the basement cell walls of the Cardston Courthouse or, on the opposite side of the law, North West Mounted Police members’ initials carved into the sandstone outcrops overlooking Police Coulee at Writing-On-Stone Provincial Park. These special cases contribute to heritage value rather than obscure or detract from it. Read more

In Search of Historic Colours: The Empress Theatre Marquee

The historic downtown of Fort Macleod, one of two Provincial Historic Areas in the province, is well known for its impressive commercial buildings of brick and sandstone masonry. Collectively, these Classical Revival buildings exemplify an Edwardian commercial streetscape just prior to the First World War.

One of the main street’s crown jewels is the Empress Theatre, an elegant brick building with decorative sandstone details built in 1912. Historically a hub of the town’s social life, the theatre hosted plays, vaudeville acts and performers from Alberta, across North America and even overseas, as graffiti preserved in the original basement dressing rooms attests to this day. The original façade was theatrical in its own right and featured a grand arched entrance and recessed box office. As tastes changed and motion pictures grew in popularity, the original entry was enclosed to provide a lobby and concession, the auditorium was renovated with plush upholstered seats in the Art Deco style and neon tulips mounted on the ceiling, and a bold new neon sign and marquee replaced the original blade sign on the front facade. These 1930s and 1950s renovations added layers of architectural history and significance to the building and contributed to its designation as a Provincial Historic Resource in 1982.

The Town of Fort Macleod owns the theatre and has embarked on an extensive rehabilitation project that includes rehabilitation of the historic neon marquee. The marquee was refurbished in the late 1980s by Fort Macleod’s Main Street Project but a generation of exposure to the elements has taken its toll on the galvanized sheet metal, paint, and fragile neon tubing. Removal of the signs for other façade repairs was an ideal opportunity to re-examine and document the marquee’s colour history. Read more

The Butterfly Effect

Peeling paint and powdering plaster were the first indications something was amiss at the Blairmore Courthouse, a Provincial Historic Resource in the Crowsnest Pass. A leak in the cedar shingle roof, replaced just the previous year, was immediately suspected. Detailing around the dormers in particular, part of the 1922 building’s distinctive Spanish Colonial Revival design by architect R.P. Blakey, is tricky and vulnerable to water penetration.

Nippon School of Technology, which owns the building and runs a technical school and exchange program for Japanese engineering students there, inspected the roof from the attic and found no active leaks. Puzzled, N.I.T. engaged a conservation architect to inspect the building and identify sources of moisture causing the paint and plaster failure. The findings were at once surprising and (in hindsight) credible.   Read more
