Design of Villa Borghese began at the start of the 17th Century when Pope Paul V Borghese was elected. Its style resembles that of city villas from 100 years earlier. The gardens were especially cared for—aviaries were added to house exotic birds and areas of the gardens were stocked with peacocks, ostriches, gazelles and even lions. Over the years, the garden was altered into an English-style space designed by Jacob Moore. One of the park's loveliest areas is the Lake Garden, which is enclosed by a railing that emphasizes the lake's irregular shape. In the center of an artificial island, a temple was built dedicated to Aesculapius. The famous Square of Siena has been the scene of horse-jumping and carriage-racing competitions since it was first built.
