The facade was cased in Portland stone in 1735. On the north side of the west wall is a modern memorial to those of the Commonwealth (or 'Roundhead') party who are buried within this 'parliamentary' churchyard. In a niche over a doorway (no longer in use) in the east wall of the church is a bust in lead of King Charles I. In this position he defiantly faces the statue of Oliver Cromwell standing outside Westminster Hall on the other side of the road
