Mr W. F. Grimes, Keeper of the London Museum (Museum of London) assisted by a volunteer, archaeological worker, Miss Adrienne Farrell, in the excavations at Monkwell Street in the City of London. In 1947, the Roman and Medieval Excavation Council under the direction of Mr Grimes, systematically explored the area laid waste by the blitz before building work began again in the ravaged area lying just to the north of St. Paul's Cathedral. The excavations eventually unearthed substantial remains of a Roman fort.
