Camulodunum was a Roman town and now modern-day Colchester. The town claimed to be Britain's oldest town. Camulodunum was founded in the late 1st century BC. It was originally a Roman legionary base constructed in the 40s AD on the site of a former Brythonic-Celtic fortress after the conquest lead by Emperor Claudius. The town included a large classical temple, two Roman theatres (one of them being the biggest in Great Britain), several temples, Britain's only known chariot circus, Britain's oldest and first town walls, several large cemeteries, and many mosaic pavements.
The walls around the town were built in 60/61 AD after the original town was destroyed. A majority of the original wall still remains today and stands at a height of 6 m. An old Roman gate also remains within the town.
