COLCHESTER, ENGLAND—Archaeologists have known about the arcade that had been built at the Temple of Claudius in Colchester for some 60 years, but the demolition of a modern office block has uncovered evidence that the covered walkway was the largest in Roman Britain. The arcade was built in the first or second century A.D., following the destruction of Colchester during Boudicca’s rebellion. “Its closest rival in terms of size stands in what was Gaul, in northern France, and shares some of the architecture we can see in Colchester today,” Philip Crummy, director of the Colchester Archaeological Trust, told The Telegraph. “The original arcade and its grand columns are similar to those you see in Bath, at the Roman Baths. It really is an extraordinary find and confirms the grandeur and richness of its Roman culture,” he said. For more on the Roman period in England, go to "What’s in a Name?"
