History
Dharahara is actually the second such tower made by Bhimsen Thapa. The original Bhimsen Tower was built in 1824 and was 11 stories high, 2 stories taller than Dharahara. Dharahara was built for queen Lalit Tripura Sundari, who was the niece of Bhimsen Thapa. She wanted a tower of her own next to Bhimshen's Dharahara.
