Parts of the exterior of the building, as it was in 1948, can be seen in The Red Shoes, including Mart Street, which defined the edge of the Opera House at that point, before Covent Garden redevelopments removed it. The Bow Street (public) and Floral Street (stage door) entrances are shown clearly. More details.
