Menai Suspension Bridge

The Menai Suspension Bridge is a Grade I listed structure featuring coursed rubble Penmon masonry with ashlar facings on its tapered suspension towers, also known as 'pyramids'. The bridge deck is suspended by a system of 16 chains, originally made of iron but now constructed from steel, which extend down into the rock at both ends. The bridge has four arches on the Anglesey side and three arches on the Bangor side, supported by tapered piers. Architectural details include voussoirs, impost bands, and a bracket cornice above the arches. The later metal pedestrian walkways are supported by additional brackets, while the original design included only a narrow central pavement. Each carriageway passes beneath the towers through semi-circular arched openings, which are complemented above by paired blind recesses that feature inscribed tablets. The handrails extend to the low tapered piers, which have pyramidal caps at each end. On the mainland side, trellised railings continue on either side and curve around to end at similar piers with panelled recesses.

At the mainland end of the bridge, the suspending members connect to the former Toll House, a low three-storey building faced with classical ashlar and featuring channelled rustication on the ground floor. The building has a three-bay front facing the bridge, with broad and taller end pilasters and arched entries. The central bay is advanced and taller, while the flanking bays contain 12-pane sash windows set below blind recessed panels. The ground floor features arched openings that create a 'loggia'. The side elevations also have a similar two-bay design. The rear of the building ramps down and has been partially modernised. Additional toll houses were constructed at both ends of the bridge later on.
