Description

Chemistry Lock and sluice is a canal lock and sluice built around 1775 by Samuel Weston for the Chester Canal Company. It is constructed from red sandstone and brick. The lock chamber features brick walls with patches of large sandstone blocks, and the upper end of the chamber is segmental in plan. Both pairs of lock gates have been replaced with steel, and there are sandstone copings along with a sandstone-lined sluiceway.
