The Temple of Claudius or Temple of the Deified Claudius was a large octastyle temple built in Camulodunum, the modern Colchester in Essex. The main building was constructed between 49 and 60 AD, although additions were built throughout the Roman-era. Today, it forms the base of the Norman Colchester Castle. It is one of at least eight Roman-era pagan temples in Colchester, and was the largest temple of its kind in Roman Britain; its current remains potentially represent the earliest existing Roman stonework in the country.
