Appraisal
This lock was named for the Earl of Westmoreland, who laid the first stone at this site in 1790. The chambers exhibit good quality stonework, with attractive sloping edges to cope with the change in height between the lower and higher levels. One of a number of double-chambered locks on this stretch of the canal, it attests to the skills of the engineers employed by the company. The setting of the lock is enhanced by the presence of a number of other industrial structures, including Westmoreland (now Crossguns) Bridge, the adjacent railway bridge, the former North City Flour mills and a former railway siding. The Royal Canal Company was established in 1789 to construct a canal to provide freight and passenger transport between Dublin and the River Shannon.
