Temple of Claudius in Colchester

The Temple of Claudius stands at the heart of Colchester, built between 49 and 60 AD as the largest Roman temple in Britain. Its octastyle design followed Vitruvius’ classical rules, with a 285-square-metre cella and a 20-metre-high frontage. The podium survives today beneath Colchester Castle, making it one of the earliest Roman stone structures in the country. The temple was dedicated to the deified Emperor Claudius and became the centre of imperial worship in Roman Britain. After the Boudican revolt in 60–61 AD, it was rebuilt and enlarged, remaining a key public building for centuries. Fragments of marble, bronze letters and a Chi Rho potsherd suggest later Christian use in the 4th century. Visitors enter the castle’s vaults to see the temple’s surviving podium from below. Above ground, parts of the precinct wall and a monumental arch from the entrance survive near the High Street. The cella’s sturdy walls once sheltered refugees during the revolt, and its bronze doors were later torn away.
