This could be considered Europe’s oldest “living” garden, given that it was established alongside the initial works on the Great Mosque, under Abd al-Rahman I in 784. It is an enclosed area measuring approximately 50 m x 30 m, divided into three parts, each with a beautiful Renaissance-style fountain in the centre. It originally contained plants such as pomegranate, cypress and palm trees. Today it has 98 orange trees planted in rows that date back at least to the end of the 18th century.
