The Pantheon was a place of public entertainment on the south side of Oxford Street, London, England. It was designed by James Wyatt and opened in 1772. The main rotunda was one of the largest rooms built in England up to that time and had a central dome somewhat reminiscent of the celebrated Pantheon in Rome. It was built as a set of winter assembly rooms and later briefly converted into a theatre. Before being demolished in 1937, it was a bazaar and a wine merchant's show room for over a hundred years. Marks and Spencer's "Oxford Street Pantheon" branch, at 173 Oxford Street now occupies the site.
