The discovery and study of The Ancient City Of Sigiriya in Sri Lanka has illuminated urban planning from the era of King Kasyapa’s reign, 477-495 CE, to archaeologists. Among the most important aspects of these ruins are the oldest landscaped gardens in the world. The gardens of the palace of King Kasyapa were divided into three: the water gardens, cave and boulder gardens, and terraced gardens. This discovery has allowed archaeologists to develop their knowledge about the history of landscape gardening. With the gardens’ former glory partially concealed from view in the present day, it is unlikely that anyone will ever fully understand, visualise, and recreate the way these gardens existed in the ancient world.
