The Mughal emperors were very much interested in literature, art and architecture. Babur, in his autobiography, described his interest in planning and laying out formal gardens, placed within rectangular walled enclosures and divided into four quarters by artificial channels. These gardens were called chahar bagh, four gardens, because of their symmetrical division into quarters. Beginning with Akbar, some of the most beautiful chahar baghs were constructed by Jahangir and Shah Jahan in Kashmir, Agra and Delhi.
