Kathmandu was once one of three equal cities, the other two being Bhaktapur and Patan. Bhaktapur (also known as the ‘temple city’) is located some 12km (7.5 miles) from Kathmandu in the eastern part of the valley. The Kathmandu Valley’s rich cultural and natural heritage has prompted UNESCO to list seven World Heritage Sites in the area. The National Art Gallery, located in the old Malla Palace, has unusual, colorful animal paintings on the second floor that are worth a look. Other museums in Bhaktapur are the National Woodworking Museum, showing fine examples of Newari woodcarving (for which the city is renowned), and the Brass and Bronze Museum, both in Dattatreya Square.
