Walbrook Ward. One of the 26 wards of London, and so called from the brook by the City wall. Stow enumerates five churches in this ward:- St. Swithin-by-London-Stone; St. Mary Woolchurch; St. Stephen’s, Walbrook; St. John-upon-Walbrook; St. Mary Bothaw. Two alone were rebuilt after the Great Fire – St. Swithin’s, London Stone, and St. Stephen’s, Walbrook. The Mansion House is in this ward.
