Wharf called " Powyls Wharffe," alias "Sondayes wharffe," in the west part of the common water called the common Watringplace in parish of St. Andrew at Baynards Castle, 3 Eliz. (Lond. I. p.m. I. 220).
First mention: " la Watergate" of Chastelbaynard to be cleansed, 35 Ed. III. (Cal. L. Bk. G. p.125).
Described as the " Watergate in the Black Freers," 1565 (Lond. I. p.m. II. 73) in parish of St. Andrew in the Wardrobe, and as in the parish of St. Benedict Woodwharf, 1568 (ib. 121), so that perhaps it may have been on or near the boundary of the two parishes.
