Nearby is the Bön Gurugem Monastery. Tsaparang is a huge fortress perched on a pyramid-shaped rock rising about 500 to 600 feet (152 to 183 m) at the end of a long narrow spur. It contains numerous tunnels and caves that have been carved out of the rock. At its base was a village where the common people lived. Above them were two public temples - the Lhakhang Marpo (Red Chapel) and the Lhakhang Karpo (White Chapel), and quarters for the monks. Further up, ascending a twisting stone staircase in a tunnel, were the royal quarters, and at the very top, the summer palace.
