From Lonely Planet: "Bhaktapur, also known as Bhadgaon or the City of Devotees, is the third major town of the valley and in many ways the most medieval. Since the major German-funded Bhaktapur Development Project in the 1970s, it has been a much cleaner and tidier town, but there's still a distinctly timeless air to the place."
"The oldest part of the town is around Tachupal Tole (Dattatraya Square), to the east. Bhaktapur was the capital of the whole valley during the 14th to 16th centuries and during that time the focus of the town shifted west, to the Durbar Square area. Much of the town's great architecture dates from the end of the 17th century during the rule of King Bhupatindra Malla."
