Temple of Claudius, Colchester

The Temple of Claudius (TEMPLVM CLAVDII) or Temple of the Deified Claudius (TEMPLVM DIVI CLAVDII) was a large octastyle temple built in Camulodunum, the modern Colchester in Essex. The main building was constructed between 49 and 60 CE, 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.

After the Roman conquest of Britain led in person by the Emperor Claudius in 43 CE, a Legionary fortress was established at Camulodunon, the Iron Age capital of the Trinovantes and Catuvellauni tribes. This fortress was later converted into a town for retired soldiers in 49 CE, and was renamed Camulodunum, a Latin rendition of the Celtic name of the site. The town was the capital of the new province of Britannia, and had several public building befitting its status. These included a theatre, a curia (council chamber), forum and a large classical-style Temple. Construction of the Temple began during Claudius' reign, and was dedicated to him after his death in 54 CE, with the official name of the town becoming "Colonia Claudia Victricensis" (The City of Claudius' Victory) and the Temple becoming the "Templum Divi Claudii" (The Temple of the Deified Claudius). The Temple was the centre for the Imperial Cult in the province, as is mentioned in Seneca's 1st century book the Apocolocyntosis, in which he mocks both the deceased Claudius and the Britons for their supposed piety towards him.
