Part of the Hezuo Monastery, this nine-story tower was built in 1678, but was burned down during the Cultural Revolution. In the late 1980s, government officials allowed the tower's rebuilding, which was completed in 1994. It's worth a rickety climb up the nine floors not only for the artifacts but also for the decent view of the city from the top. A nice monk named Chinpa who oversees the grounds may invite you in his office for tsampa and tea if you speak a bit of Chinese or Tibetan.
