Construction of the Shalamar Gardens in Lahore began on the 6th of June 1641 and took 17 months and 14 days to complete. The project was managed by Khalilullah Khan in cooperation with Mulla Alaul Maulk Tuni during the reign of Emperor Shah Jahan.
The land originally belonged to the Arain Mian Family of Baghbanpura. Mian Muhammad Yusuf ceded the land of Ishaq Pura to Emperor Shah Jahan in exchange for governance of the gardens, a custodianship that lasted for over 350 years.
The Shalamar Gardens contain a total of 414 fountains that discharge into wide marble pools known as haūz. There are 105 fountains on the upper level terrace, 152 on the middle level terrace, and 153 on the lower level terrace.
The Shalamar Gardens were nationalised in 1962 by General Ayub Khan because leading members of the Arain Mian family had opposed his imposition of martial law in Pakistan. This event ended the family's 350-year custodianship and transformed the site into a public monument managed by the state.
The Shalamar Gardens are laid out in the form of a rectangle aligned along a north-south axis, measuring 658 metres by 258 metres. The site covers an area of 16 hectares with each terrace level standing 4 to 5 metres higher than the previous one.
