No. 4 Gasholder

No. 4 Gasholder was built in 1890 by Hanna Donald and Wilson Ltd for the guide frame and James Goldie and Son for the tank, serving the Paisley Gas Light Company. The structure features a two-tier circular frame that stands 23 metres tall, supported by 18 cast iron Doric columns on plinths, which are braced by lattice girders with a guilloche pattern. Each plinth displays cast panels of the Paisley town coat of arms, and some have dated makers' panels. The gasholder includes two telescopic iron-sheeted shells, each 18.25 metres in diameter, situated in a sunken brickwork tank. Repairs to the lift sheeting were made around 1963, and in 1992, a new concrete base was poured to address subsidence issues. In 2000, lubrication systems were installed, and the grip carriages were overhauled. The shells and the tank of No. 4 Gasholder are excluded from the listing as per the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.
