Balkerne Gate

Balkerne Gate is a 1st-century Roman gateway in Colchester. It is the largest surviving gateway in Roman Britain and was built where the Roman road from Londinium intersected the town wall. It is a Grade I listed building.

History
The gate, which is the best-preserved Roman gateway in the country, was built c. AD 70–96. The gatehouse, which originally had two main arched passageways with separate arched footways on both sides, has largely disappeared. The remaining gateway which we see today is the south-side arched footway; however, the remains of a guard tower are also visible. From The Balkerne Gate, Colchester by R.E.M. Wheeler (1920): "The gate consisted of two broad carriageways, each 17 ft wide, flanked by two footways, each about 6 ft wide. The whole gate projects 30 ft in front of the town wall, and the total extent of the frontage is 107 ft."

Structure
Roman town gates sometimes had as many as three entrances but were usually limited to one or two. The Balkerne Gate, however, had four gates, and unusually wide carriageways.

There are no other quadruple gates in Britain but there are a few elsewhere in Europe; for example, the Porte d'Auguste at Nîmes, the Porte Ste. André and the Port d'Arroux at Autun, and the Palatine Towers at Turin.
