Barkhor Mani Lhakhang Lhasa

On the northern section of the Barkhor Circuit is a small building on the right, set off from the main path. This is the Mani Lhakhang, a chapel that houses a huge prayer wheel set almost continuously in motion. To the right of the building is the grandiose entrance of the former city jail and dungeons, known as the Nangtse Shar.
