 Classical architecture continues along the path around the lake , with the " Temple of Flora " , a hidden summerhouse , and the " Temple of Daphne " , both reminiscent of a small temple on the Acropolis . Another hidden temple , the " Round Temple " , has a curved loggia . Nearer the house , screening the service wing from view , is a Roman triumphal arch , the " Temple of Apollo " , also known ( because of its former use a venue for cock fighting ) as " Cockpit Arch " , which holds a copy of the famed Apollo Belvedere . Close by is the " Temple of Diana " , with a small niche containing a statue of the goddess . Another goddess is celebrated in the " Temple of Venus " . Below this is an Exedra , a grotto ( known as Venus 's Parlour ) and a statue of Mercury . This once held a copy of the Venus de ' Medici ; it was demolished in the 1820s but was reconstructed in the 1980s and now holds a replica of the Venus de Milo .
