1. The Shoebox Community Hub, Castle Meadow 

A historic street lurks below this community space, with a choice between the Hidden Street Tour and Lantern Light Underground Tour in the dark. 

This genuine medieval street was built in the old Castle Ditches and there are buildings that date back to the 15th century, including a weavers' cottage and a merchant's house.

Escape game Secrets of the Tunnels also takes place there and you can book all three activities on The Shoebox Experiences website.

2. The Undercroft Gallery, Market Place

The Undercroft is an art space beneath the Memorial Gardens at the top of Norwich Market and it can be hired by artists from Norwich City Council. 

The space was previously used as a storage area for the market traders, but it was cleaned up and refurbished and it now hosts regular exhibitions and performances.

While it is closed during the winter, visit The Undercroft website and social media pages for updates on upcoming shows.

3. The Halls, St Andrews Hall Plain

The Halls is the largest remaining friary complex in the UK and one of the oldest spaces there is The Crypt.

The Crypt features a magnificent vaulted brick ceiling, which dates back to 1307, and it can be hired for events, which includes the use of Becket’s Chapel.

Tickets are now on sale for Norfolk Nightmares there on Sunday, March 19 and Sunday, March 26 at 7.30pm, with local ghost stories told by Raconteur Theatre Company.

4. Museum of Norwich at the Bridwell, Bridewell Alley 

The Museum of Norwich runs the Building History Tour, which includes admission, on the first Saturday of each month at 11am, 12noon, 1.30pm and 2.30pm and it can be booked online or over the phone.

It explores the heritage of the museum site, taking a closer look at the magnificent medieval flint wall and a walk around the largest vaulted undercroft in the city.

The undercroft held inmates when the building was a Bridewell (a house of correction and prison) and an inventory of 1813 lists posts and chains.

5. Norwich Guildhall, Guildhall Hill

This is England’s largest and most elaborate provincial medieval city hall and it was at the centre of city government from the early 15th century until it was replaced by City Hall in 1938. 

The exterior also provides an excellent example of the flint work that Norwich is known for and the undercroft was used as a dungeon for criminals. 

The Guildhall often opens up for the public to explore for free on the Norfolk Heritage Open Days, which will return in September.
