Lighthouse Central, West Loan, Prestonpans

Lighthouse Central in Prestonpans is a simple neo-Gothic building designed by R Thornton Shiells in 1878. It features a gabled design with four bays on the sides, a porch, and stair wings at the front (east), along with a vestry at the rear. The structure is primarily built from grey sandstone, squared and snecked at the front, while the sides are made of random rubble, with dressings that are stugged and droved.

The east elevation is dominated by a symmetrical gable that includes a large pointed-arched three-light window with plate tracery. Above this window is a unique Gothic stone bellcote, which is part corbelled and octagonal, featuring cusp-headed openings and gablets, topped by a seemingly truncated ashlar polygonal roof. The gabled porch is set forward and has a doorway in a moulded pointed arch, flanked by stair wings that lean-to, each with two small lancet windows at the front. The outer bays are flanked by single moulded lancet windows, and all corners are supported by simple ashlar buttresses.

The side elevations are symmetrical with four bays, each showcasing four moulded lancet windows separated by simple ashlar buttresses. The west elevation mirrors the front with a large central pointed-arched three-light window with plate tracery and features an elliptical slit opening in the gablehead. The vestry is positioned at a lower level and is flanked to the north by a bipartite lancet window. All side windows are lancet-shaped with horizontal bars, typically four or five in number. The roofs are covered in grey Welsh slate, while the main roof has a decorative toothed pattern below the ridge made of grey-green graded Westmorland slate, with a ridge finished in decorative red clay tiles. The skews are in saddleback ashlar, and the east gable features a complex Gothic bellcote, while the west gable has a stair finial.

Inside, the building has a pleasing simple design with a roof supported by Gothic braces that rest on slim iron columns, which also support side galleries. The stained glass includes text panels and motifs of intertwining fruit and flowers, created by Ballantine and Gardiner in 1896.

The entrance is marked by plain square gatepiers made of ashlar with pyramidal copes, flanked by low walls constructed from squared and snecked sandstone with an ashlar cope and modern railings. The side walls are made of random rubble.
