The Rotunda on Woolwich Common, in south-east London, is a former artillery museum which was established in 1820. The building was originally a very large bell tent erected in St. James's Park in 1814 for a special exhibition and premature victory reception of the allied sovereigns in the Napoleonic Wars but its architect John Nash turned it into a permanent structure with a lead roof and central supporting pillar. In 1973 the Rotunda was designated as a Grade II* listed building. * Obsolete sign near the entrance * Rotunda and Napier Lines corral * Tent-roof detail * View from the east
