Paduraksa, also known as kori is a type of gateway covered with towering roof that can be found in the island of Java and Bali, Indonesia. This architectural feature is commonly found in buildings from the classical Hindu-Buddhist period of Indonesia. Paduraksa marks the threshold into the most sacred space (the inner sanctum) within a religious compound, a cemetery, or a palace. In Balinese architecture, an elaborately decorated towering paduraksa is often built as the temple's most imposing structure.
A paduraksa is basically a gateway in the form of a candi. The structure consists of three parts: the base, where a flight of steps are located; the body where the entrance opening is located; and the crown, with its stepped profile characteristic of a candi. The entrance opening is sometimes equipped with a door made of finely carved wood.
One of the oldest surviving paduraksa gate is Bajang Ratu in Trowulan, an elegant red brick paduraksa gate dating from the mid-14th century Majapahit. The Bajang Ratu gate is adorned with a bas reliefs depicting the story of Sri Tanjung and Ramayana. The form of the structure is tall and slender, rising to a height of 16.5 metres and displaying intricate relief decoration, especially on the roof section.
While the basic form of a paduraksa is of a stepped candi, it can be heavily decorated with ornaments, figures, and symbols. In Bali, the crown of the paduraksa is decorated with flame-like ornaments and celestial figures. The menacing head of the bhoma or fierce kala is often carved over the opening, while a lion-like effigies, or a pair of fierce giants of dvarapalas, guard the sides of the entrance. Both menacing figures of kala's head and dvarapalas door guardians, are believed to have protective property; to repel and drive away evil spirits from entering the compound.
The main kori that marks the threshold into the inner sanctum of the main shrine is known as the kori agung ("great kori"). A paduraksa in the Islamic cemetery complex of Sendang Duwur contains a mysterious wing-like feature thought to represent the wings of the meru; this might be associated with the celestial bird garuda.
