As its name implies, the Summer Palace was used as a summer residence by China's imperial rulers - as a retreat from the main imperial palace now known as the Palace Museum (or 'Forbidden City') - a pleasureground in the countryside, yet near to the city. The Summer Palace is virtually a museum of traditional Chinese gardening that uses rocks, plants, pavilions, ponds, cobble paths and other garden styles to create a poetic effect between different scenes. When you stroll around the Summer Palace, you will constantly find the area changing.
