Interior view of the Colosseum, Regent's Park, Marylebone, London, 1829; showing workmen, including painters suspended in cradles, preparing Thomas Hornor's panorama of London as seen from the top of St Paul's Cathedral. The passage to the left and the tented roof prevented visitors from seeing the panorama as they entered. The spiral staircase and a lift took them to viewing platforms modelled on the cathedral's dome.
