Archaeology
Most of the archaeological evidence for the second Baynard's Castle comes from excavations in 1972–5, before the construction of Baynard House. Parts of the north wing of both the original house and extension were found, including the north gate and gatetower, and the cobbled entrance from Thames Street. Two E-W "limestone" walls were found; the excavator suggested that the more northerly one was the curtain wall of the pre-1428 castle, and the other was a post-1428 replacement. The latter was surmounted by a brick facing with a rubble core, to which a rectangular pier was attached. The castle had foundations of chalk, ragstone and mortar and was built entirely on reclaimed land. Several phases of building in the late 17th century were also identified. Excavations in 1981 at the City of London Boys' School uncovered the SE corner tower of the Tudor castle. The London Archaeological Archive codes for the excavations are BC72/GM152, UT74, BC74, BC75 and BYD81.
