NOTES: The circular monument, commemorating the scholar Dugald Stewart, was a reproduction of the Lysicrates monument in Athens by W.H. Playfair in 1831; the gothic-revival Old Observatory House was designed by James Craig.
NOTES; Built for the University of Oxford by the Radcliffe Trustees, this observatory was begun to the design of Henry Keene in 1772, but after his death completed in 1794 to a different design by James Wyatt.
