Post Office

Italianate style Post Office composed of 2 conjoined ranges of scribed stucco walls, of which the N range is 2-storey with attic and has a hipped slate roof with raised lantern light, while the S range is 3-storey and has a gabled slate roof. In the 2-window N range the arcaded lower storey has keyed round heads to the windows and the doorway on the L side, with an impost band. The double doors are replaced in the original opening, but its overlight and the remaining windows retain their original marginal iron glazing bars. The windows have a corbelled sill. In the upper storey the windows have stilted heads with keystones and impost and sill bands, and 2-light casements below transoms. Below the impost band is a central clock. A deep bracketed cornice is below the parapet, which is surmounted by a Royal Arms.

The 2-window S range projects slightly in front of the N range. In the lower storey, on the L side, is a round-headed window with marginal iron glazing bars and corbelled sill, while on the R side is a tripartite sash window with fluted shafts and architrave. On the R side of this window is a tablet commemorating Sir William Preece (1834-1913), chief engineer to the Post Office, pioneer of wireless telegraphy and a native of Caernarfon. In the middle storey are 4-pane sash windows under keyed segmental heads with impost bands, similar to the N range, while the upper storey has plainer 4-pane sash windows and corbelled sills. The eaves are bracketed.

The L-hand elevation facing Chapel Street has 5 tall segmental-headed windows incorporating hopper lights in the lower storey, beyond which the wall is aligned differently and has a smaller window, then a pair of taller windows further L. Above the tall windows are shorter segmental-headed upper-storey 4-pane sash windows, although there is no window set back from the R end.

Further behind is a 4-window rear wing of snecked rock-faced stone and Bath stone dressings to 6-pane horned sash windows, and slate roof with skylights. It is single-storey, except for the L hand which has a second storey under a coped gable, with 6-pane sash window in the upper storey and a small-pane horned sash window in the side wall overlooking the roof of the remainder of the wing. The R gable end facing Segontium Terrace is pebble-dashed and has 4-pane sash windows.
