The eastern end of Gallions Reach

Gallions Reach is a stretch of the River Thames between Woolwich and Thamesmead.[1] The area is named for the Galyons, a 14th-century family who owned property along this stretch of the river,[2] and places, including street names, on both sides have been named after it.
