I spent the rest of the day at what they call the spiritual heart of Tibet, the Jokhang Temple, one block away from my hostel (built in the mid-seventh century by Songzain Gambo for the Tang Princess Wen Cheng and Nepalese Princess Bhrikuti).
It is a fairly large complex of shrines and galleries filled with images, door carvings, and many treasures of Tibetan art.
