Holyhead Breakwater

Breakwater starts with an extended and consolidated rocky headland of rubble fill with massive squared blocks to outer revetments. Masonry landing stage to harbour side. Narrower pier runs NW from junction at ashlar drum with rope-mould cornice; massive attached parapet. Broad elliptical string course to seaward side with rubble blocks below; raised walkway and protective wall with oversailing cornice. Cyclopean dressings to inset stairways (with stone barriers) flanked by concave refuges to lower deck; alternating masonry blockhouses with central arched openings. Occasional waisted bollards and inset stairways to harbour edge of lower deck (formerly with tramway lines). Towards outer end is a modern masonry exedra facing harbour. Cyclopean steps flanked by screen wall with rope-moulded turret lead up to outermost platform with lighthouse and parapets. Outer ovoid platform was formerly a gun platform.
