Saint Paul’s Cathedral is one of London’s most recognizable monuments; its dome has dominated the city’s skyline for hundreds of years. Indeed, specific views of the church are protected by law. The dome is rather unique for having three shells: the outer dome, a concealed brick cone for structural support, and an inner dome. The church itself has been the setting for such major events as the wedding of Diana, princess of Wales, and Charles, prince of Wales (later Charles III), in 1981 and the funeral of former prime minister Winston Churchill in 1965.
