Stromness Museum, 54 Alfred Street, Stromness

Stromness Museum, located at 54 Alfred Street, Stromness, is a two-storey, three-bay symmetrical former Town Hall built in 1858, with subsequent alterations and additions. The building exhibits classical detailing.

The principal, south elevation features an advanced, pedimented porch at the centre. A boarded door with a rectangular fanlight, inscribed "MUSEUM," is set within the porch, flanked by two narrow windows. There is a window above the door on the first floor. Windows are present at each floor in each bay flanking the porch. To the right of the porch is a single-storey, two-bay pitched-roof wing (No. 54), connected by a flat-roofed, rectangular two-bay porch that spans the junction between the main block and the wing. A boarded door and a window are located on the right side of the porch.

The west elevation, facing Alfred Street, is a four-bay gabled wall. A moulded architraved doorway with a deep-set timber panelled door and a large rectangular fanlight is positioned in the bay to the left of the centre. A blocked window sits to the outer left, above which is a first-floor window. Another ground floor window is situated to the right, above which is a blocked window on the first floor. A window is on the right side, and another is on the upper floor. A multi-flue gablehead stack rises above this section.

The east elevation, facing the seafront, comprises a gabled wall for the main block with a lean-to porch, recessed to the center. An advanced gabled single-bay block, containing a bipartite window, extends from the outer left side (No. 54). To the right is a pitched, two-storey, three-bay rectangular cottage. This cottage has a gabled end wall projecting from the right-hand bay and regularly placed windows on the south elevation. A timber panelled door is centrally located on the ground floor, and a window is set to the right of the cottage.

The north, or rear, elevation is irregularly fenestrated.

The windows are primarily timber sash and case windows with 3, 4, 7, 8, and 12 panes, complemented by fixed narrow lights flanking the doors. The roof is covered in purple Welsh slate, with a stone ridge, replacement concrete skews, coped concrete ashlar stacks, moulded cans, and predominantly cast-iron rainwater goods, with some uPVC replacements.

The interior features a black and white encaustic tiled porch, part-glazed timber panelled two-leaf vestibule doors, architraved timber panelled doors, timber skirting boards, and plain cornices.
