Banteay Srei is located near Phnom Kulen in Northeast Angkor Thom. It is a unique and exquisite building among Angkor's monuments. It is famous for its bright colors and exquisite reliefs. It is known as the “Gem of Angkor Art”. The name Banteay Srei means “women's castle”, which is supposed to have been constructed and carved by women. Its Central Tower and large library contain a large number of statues. Its walls, columns and other architectural surfaces are full of reliefs, complex shapes and soft lines. Unlike the green sandstones used in most of the Angkor monuments, Banteay Srei was built using Khmer-specific red clay, which is extremely colorful and keeps the carvings intact.
