The next stop was Patan Durbar Square. Patan, also called Lalitpur, is the oldest city in the Kathmandu Valley and one of the oldest Buddhist cities in the world. It is thought that it was built by the emperor Ashoka, who I learned about in my History of Ancient India class in college. It was interesting to see that history in action!
It's a center for both Hinduism and Buddhism and has 55 major temples. The current buildings were primarily built in the 1600s.
I unfortunately don't have a ton of information about the square itself, but it was incredibly beautiful.
