St Mary-le-Bow /sənt ˈmɛəri lə ˈboʊ/ is a historic church rebuilt after the Great Fire of 1666 by Sir Christopher Wren in the City of London on the main east–west thoroughfare, Cheapside. According to tradition a true Cockney must be born within earshot of the sound of Bow Bells (which refers to this church's bells rather than St Mary and Holy Trinity, Bow Road, in Bow, an outlying village until the 19th century).
