A six-month excavation by Museum of London Archaeology at the construction site of Bloomberg’s future European headquarters in the center of London has revealed layer upon beautifully-preserved layer of Roman habitation from the earliest days in 40 A.D. to the collapse of Roman rule in the 5th century.

Just a few yards from the Thames and waterlogged by the Walbrook River, one of London’s famous “lost rivers” that disappeared under the city when they were diverted into culverts to make way for development, the three acre site is replete with organic remains in incredible condition.

Entire streets have survived, as have the remains of shoulder-high woodenwalls, extensive wood foundations, complex waste drainage systems, a deep wooden well and a wooden door that is the second Roman wood door ever discovered in London.
