Maddermarket Theatre, Norwich

The Maddermarket Theatre is a British theatre founded in 1921 by Nugent Monck. The building was constructed in 1794 as a Roman Catholic chapel, but it changed roles often over the years. After it functioned as a chapel but before its use as a theatre, the Maddermarket was a baking soda factory, a grocery warehouse and a Salvation Army hall.

The theatre gets its name from the medieval market that once stood on this site. One of the primary items sold at this market were madder plants, which create scarlet dye popular in the wool trade. Madder plants can still be found near the front entrance of the Tudor-style building.

The Maddermarket Theatre is particularly known as the stomping grounds a famous Norwich ghost. The ghost of a monk has been seen around the building and across the stage. Doors that inexplicably open and close, costumes that go missing and props that are moved are blamed on this ghost.

The monk has also been credited with saving the life of an actress who was nearly crushed by falling lights. He is also said to comfort actors who forget their lines with a warm embrace.
