One of my favorite historic spots in Lahore is the Shalimar Baagh (garden).
The construction of this mughal garden began in 1637 C.E. and completed in 1641. It was designed in the lifetime of Shah Jehan and it mimiced the one built in Kashmir by his father, Jahangir.
These gardens were laid out as a ‘charbagh’ meaning quadrilateral garden based on the four gardens of Paradise mentioned in the Quran.
