Aqueduct stonework sign near Hardings Wood, Staffordshire

POOL LOCK AQUEDUCT MDCCCXXVIIII This is on the side of the aqueduct (built in 1829) carrying the Macclesfield Canal across the Trent and Mersey Canal a few metres north-west of the paired locks (No 42). Only one lock is referred to because the second was built in the 1830s after the Macclesfield Canal was opened.
