Former semaphore station, subsequently converted to use as a telegraph house; one of a series built in 1841 by the trustees of the Liverpool Docks, and, like that surviving at Prestatyn, ascribable to Jesse Hartley, Chief Engineer to the Mersey Docks and Harbour Board. Originally a 2-bay rectangular structure with central stack, it was extended to the S and N later in the C19; further, modern alterations and additions.


Single-storey building, consisting of a primary rectangular block with later extension to S and with modern, flat-roofed, bow-windowed addition to north. Of whitened brick construction, the (early) additions of whitened rubble. The original section retains its contemporary slate roof with graduated courses, and has sandstone copings up to half hips (the S. extension, also slated, repeats this treatment). Central rendered chimney with clustered octagonal flues; small, plain chimney to extension. 2 recessed windows to W side (and formerly also to E), with cambered heads and modern small-pane glazing. Modern windows and openings elsewhere, including a canted bay to E. A large C19 stone tablet in the N gable bears the inscription: " Llysfaen Telegraph, built in 1841 by the trustees of the Liverpool Docks". Below, a single-storey later C19 lean-to addition of slated rubble extends the full length of the gable. To the R a modern porch has been incorporated with, projecting northwards immediately beyond, a bowed modern addition. A small, single-storey rubble addition adjoins the gable lean-to to the E; pitched, slated roof and late C19/early C20 4-pane casement to front. Beyond, a modern glazed extension.


The interior was not inspected at the time of survey (3/97).
