The siege of Kirtipur, 1757 to 1767
In the 18th century Kirtipur belonged to the kingdom of Patan and guarded the south-western approach to the valley. Prithvi Narayan Shah of Gorkha, set on conquering the valley, saw it as the key. His first assault, in 1757, failed and his commander Kalu Pande was killed. A second attack in 1764 also failed, and the king's brother Surpratap Shah lost an eye to an arrow.
The third campaign, in 1767, turned to siege. The Gorkha army cut off food and water from the ridge town for months, while the other valley kings did not come to its aid. Kirtipur surrendered. Accounts, including that of a Capuchin missionary in the valley, say the conqueror ordered the noses of the town's men to be cut off as punishment. Kathmandu and Patan fell the next year.
Kirtipur stayed a farming and weaving town until the 1960s, when Tribhuvan University, founded in 1959, built its main campus on the slopes below. The town has grown fast since, but its upper core keeps its temples and squares. Community groups have restored houses and water spouts, and a cooperative of local women opened Newa Lahana to keep Kirtipur's cooking alive.
