Description
The Clayton Tunnel North Portal Tunnel Cottage is part of the original layout of the London-Brighton Railway and dates from 1841. It is situated over the north end of Clayton Tunnel. The pointed arch of the tunnel is flanked by octagonal turrets that feature imitation machicolation, a castellated parapet, and loop lights. Above the arch, the cottage has one storey and two windows set back behind a parapet. Originally constructed of white brick, it has a hipped slate roof. On each side of the turrets, there are flanking walls that end in lower octagonal turrets. Sir John Rennie was the chief engineer for the London-Brighton railway line.
