Built between 1804 and 1809, this is among the foremost examples of Greek Revival style in England. https://www.historicengland.org.uk/listing/the-list/list-entry/1000296. Now the home of Grange Festival https://thegrangefestival.co.uk/ [Note: it is marked on Google Earth imagery as Grange Park Opera, but that seems to be a different organisation https://grangeparkopera.co.uk/ ].
