Right opposite the northeastern corner of the Grand Palace complex finds the sacred Bangkok City Pillar Shrine. According to the ancient Siamese (Thai) belief, a city pillar needs to be installed upon the establishment of a new  city to symbolize the stability of power. The new city pillar was made of teak and cassia woods gilded with gold leaves, measuring 70 inches in diameter and 107 inches in height. Both pillars are now sheltered in prang-shaped shrine, which was built at the same time with the second city pillar, together with sacred images of five protective deities (Theparak): Phra Suea Muang, Phra Song Muang, Chao Por Hor Klong, Chao Por Chetakhupt and Phra Karn Chai Si.

Many people come to see the shrine and offer up gifts at time of worship.
