Why were the gardens constructed by Babur called chahar bagh?

One of the unique features of Mughal architecture was the construction of gardens by Babur, the founder of the Mughal Empire. These gardens were called “chahar bagh”, which means “four gardens.” They were designed in a quadrilateral layout divided into four equal parts by water channels or walkways. This design was inspired by Persian ideas of paradise, where gardens symbolized heaven with flowing water and greenery, providing a peaceful and aesthetic environment.
