Rotunda

The Blackfriars Rotunda was a building in Southwark, in the modern borough of Southwark, London, in various iterations from 1787 to 1958. It was originally a museum that housed the natural history and ethnographic Leverian collection and was later used as a music hall, a centre for radical meetings for the Rotunda radicals group, and a pub.
