This record was the subject of a minor enhancement on 27 November 2014. The record has been generated from an "old county number" (OCN) scheduling record. These are monuments that were not reviewed under the Monuments Protection Programme and are some of our oldest designation records.

The monument includes a medieval undercroft, or vaulted chamber, believed to date to the mid 13th century. It is traditionally known as ‘The Crypt’ and is situated below a modern building called ‘The Crypt Gallery’ on the east side of Church Street, near to a car park. The undercroft is constructed of at least two bays with a vaulted roof with Early English bosses. It is flint-walled and is approximately 8.2m long, 4m wide and 1.7m high. The undercroft is approached by an original stair on the east side with a corbelled roof and there are blocked pointed arches in the north and west walls. It is formerly thought to have been sited below a medieval merchant house or court house. It was originally approached by a painted arch and flight of steps on the north side and a flight of steps in the east wall. An area near the undercroft was excavated in 1993, which recorded the remains of three or four tenements.

Reasons for Scheduling

A domestic undercroft of the medieval period might comprise three, four or more vaulted bays depending upon the wealth of the owner. They were constructed of stone, fireproof and used for the storage of provisions or items of special value. Placed beneath a house they could thus be kept under close supervision. Although undercrofts are sometimes referred to as cellars, they were not necessarily built entirely below ground level, but, where they are sunken into the ground this can aid their preservation when the house either falls into disuse or is replaced by a later structure, such is the case with the undercroft below The Crypt Gallery. All domestic undercrofts of the medieval period with significant surviving archaeological remains are considered worthy of protection.

The undercroft below The Crypt Gallery, Lewes survives well with some impressive medieval architectural details. It provides an important testament to the early history of Lewes. The monument has high amenity value, as a recreational and educational resource within the town, which adds to its value and importance.
