Description of Historic Place

Casemates 57 and 58, located in the Northwest Demi-Bastion, are an integral part of Halifax Citadel, a star-shaped fort on the crest of Citadel Hill in downtown Halifax. Built into the thick rampart wall of the fortification, the escarp side of each Casemate simply displays a splayed gun port flanked by loopholes. Similar in design, both are plain vaulted bombproof structures of rectangular plan and feature a high masonry front/retaining wall pierced by window, door and ventilation openings. The designation is confined to the footprint of the buildings.

Heritage Value

Casemates 57 and 58 are a Recognized Federal Heritage Building because of their historical associations, and its architectural and environmental values.

Historical Value:
Casemates 57 and 58 are strongly associated with the defence of the British Imperial naval station of Halifax against potential military incursions by the United States following the War of 1812. The upgrade of the Halifax defences and the resulting economic benefits had a significant impact on the community of Halifax.

Architectural Value:
Casemates 57 and 58 are good examples of specialized, reinforced defensive military structures integral to a permanent mid-19th century bastioned masonry fortification. Their defensive characteristics are exemplified by their partial underground construction, and other protective features. Designed to satisfy specific functional requirements for the accommodation of smoothbore ordnance and related storage within a restricted space, these functional buildings exhibits good craftsmanship and materials.

Environmental Value
Casemates 57 and 58 reinforce the present military character of the Halifax Citadel National Historic Site setting.

Character-Defining Elements

The character-defining elements of Casemates 57 and 58 should be respected, for example:

The functional design and good quality materials, for example:

-The low profile of the structure, the casemate chimneys protruding through the parapet, the parapet surrounding the deep open stairwell that provides access to the casemates via a dressed granite stair contained within an ironstone lined areaway;
-The front exterior, or retaining wall constructed of coursed hammer-faced ironstone with a projecting cut-sandstone coping, the arrangement of openings in each bay comprising a single door flanked by windows for Casement 51, and three windows for Casement no.52, and ventilation openings for both;
-The exterior rear wall that blends in completely with and forms part of the escarp wall, each casemate having its own splayed gun port with three checks in the east jamb flanked by loopholes;
-The squared ironstone stone walls, brick vaults, of the plain interior chamber with a slight angle in the floor plan to the east side, the gun platform below the gun port, the internal opening through the party wall, the fireplaces and lamp recesses;
-The extensive use of worked granite ashlar for the stairs and the one-piece flat lintels, quoined jambs, lug sills and threshold margins;
-The earth covered, bombproof roof forming the terreplein.

The manner in which Casemates 57 and 58 reinforce the present military character of the setting within Halifax Citadel National Historic Site, as evidenced by:

-The specialized military design and materials that maintain a visual and physical relationship to the rampart/escarp wall, the terreplein and harmonize with the other buildings in the fortress.
