A city office with a hidden medieval cellar has been put up for sale.

2 Redwell Street, Norwich has a modern 20th-century shop front but has a secret lying deep below. 

Under the shopfront lies a 15th-century brick undercroft. The hidden cellar is one of around 70 known remaining undercrofts that exist in Norwich City centre. 

Their hidden underground nature has led them to survive fires and demolitions of surrounding buildings. 

This building in particular has even more history. Home of Mostyn Armstrong, a lieutenant in the Norfolk military and a local historian. 

A spokesman for Brown & Co said: "It is the presence of the undercroft, used for storage and not open to the public, that gives the building its extra special, Grade II star listing."

The property is currently rented out to two businesses who will remain in the property after the sale. It produces an income of £28,200 a year.

The office is listed for offers in excess of £375,000.
