The Tower is the king's fortress at the south-east corner of London's wall, the White Tower of the Conqueror with the ditch and outer wall that William Longchamp dug and built in 1189-91.
Whoever holds it can overawe the city: Longchamp held it against the Londoners and John's party in October 1191 until he surrendered it. The Jews of London look to the constable for protection. On 1 January 1200 it is in the keeping of the justiciar.

The Chronica stops in 1199, so for 1200 the witness is the briefer Gesta Regum, which notes John's peace with Philip, the coronation of Isabella at Westminster on 8 October 1200, and matters touching Canterbury: the archbishop Hubert Walter as chancellor, the cathedral priory's quarrel with him, and the Lambeth college dispute lately settled by the pope.

- Flowers of History, Roger of Wendover (about 1220 to 1235 at St Albans).
