Rammey Marsh Lock

Rammey Marsh Lock (No 12) is a lock on the River Lee Navigation at Enfield. The area adjacent to the lock is known as Rammey Marsh and close to the River Lee Flood Relief Channel. Rammey Marsh is marked thus on the Ordnance Survey map of 1887, named from Ramhey 1538, Rammey 1610, probably 'island (of dry ground in marsh) where rams are pastured', from Old English ramm and ēg. - (Wikipedia, accessed 2010-07-11)
