The structure of the Georgian Theatre Royal incorporates parts of the old Hospital of St. Leonard which, in the Middle Ages, was run by a strict order of nuns. One of these ladies, it is said, fell in love with a young nobleman and her feelings were not unrequited. Unfortunately, the lovers were discovered! - and for breaking her vow of chastity, the nun was thrown into a windowless room which was immediately bricked up to form the poor girl's living tomb!
A room behind the dress circle is still pointed out as the place where this macabre event took place. Even today it retains a cold and eerie atmosphere. The nun herself appears in faded grey on occasion. She is always peaceful and friendly and apparently heralds great success for the theatre's current production.
