Posterngate is situated under the Royal Bank of Scotland in Bank Street.

A posterngate is a small secondary gate that is usually added into a structure later on, as an afterthought.

A trained guide from from The Collection explained to visitors the history of the city.

The Roman limestone wall is part of the southern wall of the old city of Lincoln.

Excavations in the 1970s revealed the remains of the 4th century gateway.

The cross-section of the Roman city wall is 15 to 16 feet wide.

Trails in the stone show that a gate was used to guard the entry through Posterngate.

The ruins are accessed through a small door at the side of Royal Bank of Scotland.
