Cheltenham's amateur theatre has been putting on productions for over sixty years. Founded in 1945, the building was converted from Henry Thompson's Montpellier Baths, which first opened in 1806. Today, this small theatre offers a varied programme, which includes musicals and plays by some of the world's best-known writers, such as Michael Frayn, Alan Ayckbourn and Leonard Bernstein. Most productions are the work of dedicated amateur companies but professional companies also occasionally visit.
