Description

The Former Almonte Post Office National Historic Site of Canada is a striking building with a steep gabled roof with central clock tower and an attractive stone exterior. It is prominently located on a triangular piece of land at the corner of Little Bridge and Mill Streets in the centre of the town of Almonte, Ontario. The late 19th-century, two-and-a-half-storey, stone building is representative of the multi-use post offices designed by Thomas Fuller. Official recognition refers to the building on its legal property at the time of designation.

Heritage value

The Former Almonte Post Office was designated a national historic site of Canada in 1983 because:

  • this post office by Thomas Fuller is representative of its type;
  • having undergone no major exterior alteration, it possesses architectural merit;
  • its siting possesses integrity;

The Former Almonte Post Office epitomizes the smallest of the multi-use post offices erected by the Department of Public Works in small urban centres during Thomas Fuller’s term as Chief Architect (1881-1886). It is representative of Fuller post offices in its two-and-a-half-storey height, its use of high-quality materials, its Romanesque Revival styling, its prominent sitting, and its interior layout. Having undergone no major exterior alteration, the post office possesses architectural merit.

Character‑defining elements

Key elements that contribute to the heritage character of the site include:

  • its prominent location on a triangular piece of land at the corner of Little Bridge and Mill Streets in the centre of the town of Almonte, Ontario;
  • its Romanesque Revival style, evident in the wide voussoirs over the doors and windows, the heavy stone gables, the polychromatic wall surfaces, the rough textured stone surfaces and the heavy, almost primitive, stone detailing;
  • the three-bay, symmetrical main façade with two flanking entrances;
  • the steep, picturesque gable roof clad in copper;
  • the clock tower with its four-dial clock;
  • its picturesque silhouette created by the interplay between the elevations, frontispiece, gables and lively roof line;
  • the use of richly coloured, textured and carved stone, as evidenced in the basement walls of Beckwith limestone, the upper walls of locally-quarried North Elmsley sandstone and the window and door headings, sills and decorative elements of Nova Scotia red sandstone;
  • surviving elements of the first- and third-floor plans and detailing which include the original ground floor ceiling and two small walk-in vaults that relate directly to the original function of the building;
  • surviving interior finishes, including the moulded trim with boxed corners and bull’s eye motif around the doors and windows, the wainscoting and the staircase with heavily turned newel posts and railings;
  • the strategic use of the wedge-shaped site on a rise of land to expose the two main façades of the building.
