The Alhambra scenic area is divided into four large blocks, one of which is the Nilo Rifi Garden, commonly known as the "summer palace". It was built in the 13th century and was renovated by King Abu I Walid Ismail. It is designed to trim various geometric patterns of flowers and trees, layered around two courtyards, between the courtyards by canals. The canal is in Arabic rectangular shape, with a row of water spouts on each side. When the floodgates are opened, the water columns form an arch. The water beads are shining in the sun and are laid out in a cool place. This can understand why successive kings liked to spend the summer here.
