Queen's University Archives is located in Kathleen Ryan Hall, which was constructed as the university’s medical building. During the Second World War, the building housed biological and chemical warfare testing labs. In 1981, the building was renovated for the Archives. It now consists of a reading room, conservation lab and several climate-controlled vaults that hold university, city and private records.

But arrive early because tour capacity is limited (no pre-registration required).

Kingston’s largest commercial gallery represents 18 contemporary local artists and displays over 400 works of art. The main gallery was originally a carriage way — a passage for horses to access their stables. Behind the gallery, The Mews is now used as the framing workshop. In 2007, part of The Mews was turned into an overflow for Gallery Raymond’s regular collection.

St. Mary's Cathedral was consecrated in 1848. For the past 175 years, it has been a place of worship in Kingston. The stained glass has been called some of Canada’s finest; it was featured on a postage stamp in 2012. During Doors Open, tour guides will provide historical, architectural and spiritual information on the cathedral and its crypts.

St. George's Cathedral opened in 1827 and was enlarged in 1892. It was rebuilt after a devastating fire in 1899. Constructed of limestone and designed in the neoclassical style, it has hardly been altered since the 1899 rebuild (which basically recreated the 1892 expansion), either inside or outside. Its dome is a prominent feature of the Kingston skyline.

The Murney Tower Museum is a community museum operated by the Kingston Historical Society in partnership with Parks Canada. Located in one of Kingston’s iconic Martello towers, it is part of the Rideau Canal and Kingston Fortifications (and a UNESCO World Heritage Site). Kingston’s oldest operating museum, it features a collection of 1,000 military and domestic artifacts, portraying 19th-century Kingston.

This museum was repurposed by the Township of South Frontenac and the South Frontenac Museum Society in 2012. It was designated as a heritage site (with a particular focus on the bell tower and the windows, which were replaced per their original design). Most of the collection pieces have a local connection, having been made or used in nearby communities.

This museum was once the residence of the warden of the Kingston Penitentiary. Built by inmate workers, the home was first occupied in 1873. In 1933, most of the building was converted to administrative offices with a small apartment retained for penitentiary use. In 1985, the museum officially opened in only two rooms, but eventually became the sole occupant.

Barriefield, established in 1814, is a village overlooking the Cataraqui River. In its heyday, it boasted taverns, boat-building yards, a sawmill, blacksmiths, carpenters, shops, a village school and a church. Barriefield Village was designated as the first Heritage Conservation District in Ontario and still retains its 19th-century character. During Doors Open, join this rare opportunity for a guided village tour.
