Up above the city the mountain was carved plain and rocks were formed to build a palace without masonry being used the rocks were formed into interlocking blocks. The palaces is vast with many wondrous buildings which seems to have been designed to group people into different sections with burning chambers and sepulchres hew into the mountain.
