A prominent feature of Bayon-style architecture, dating from 1181 until 1243, is elaborate doorways. They are often shaped as a monumental tower or a smaller yet no less ornate entrance. This gopura on the west side of Ta Prohm is a classic example. Notice the columns resembling balusters flanked by foliated carvings in stone with pink and green hues. In the lintel (horizontal block) is an elaborate frieze. They are crowned inside the tympanum with a bas-relief of meditating Buddha figures.
