Rome’s largest park is Rome's favourite place to escape the city noise and bustle. Once a vast private estate, it was laid out around 1650 for Prince Camillo Pamphilj, nephew of Pope Innocent X. It's a huge expanse of rolling parkland, shaded by Rome's distinctive umbrella pines. At its centre is the prince’s summer residence, the Casino del Belrespiro , and its manicured gardens and citrus trees. It’s now used for official government functions.
