The castle foundations are built directly over the remains of the Roman Temple of Claudius, which was destroyed by Boudica in 60 AD.
The stone used to build the castle includes repurposed Roman brick and septaria, a form of local ironstone.
The keep is estimated to be roughly 50 percent larger in floor area than the White Tower at the Tower of London.
During the 17th century, the castle was used as a prison, and the upper floor was partially demolished in an attempt to pull the structure down.
The castle grounds contain a dedicated 'Castle Museum' display that highlights the site's transition from a royal fortress to a provincial gaol.
The museum collection includes the 'Colchester Vase', a rare Roman-period vessel depicting a gladiator fight.
Colchester Castle is a Norman keep built on the foundations of the Roman Temple of Claudius, dating back to the late 11th century. It stands as the largest Norman keep ever constructed in Europe. The castle houses a museum showcasing extensive collections ranging from the Iron Age to the Roman period in Britain. Exhibits include the Colchester Vase and a significant collection of Roman coins. The structure sits within Castle Park, a Victorian-era municipal park featuring extensive gardens and a boating lake. Archaeological remnants of the Roman town of Camulodunum are integrated into the museum's displays. The site currently serves as a regional heritage center focusing on Colchester's evolution as the oldest recorded town in Britain.
