A prasat ( Thai: ปราสาท, from Sanskrit: prāsāda), or more accurately, kudakhan (กุฎาคาร, from Pali/Sanskrit: kūṭāgāra) or rueanyot (เรือนยอด), is a Thai architectural form reserved for royal palaces of the monarch or for sacred religious structures. It is a building featuring an ornate roof structure, usually multi-tiered, with one or more spires. The form symbolizes the centre of the universe, which is traditionally associated with the monarch or the Buddha. [1] [2] Prasat forms are widely used in the buildings of the Grand Palace, and are also found in some Buddhist temples ( wat) and in the architecture of the temporary crematoria used for royal funerals.
Architectural historians have classified kudakhan into several categories, according to the shape of the spire: mondop-shaped, prang-shaped, mongkut-shaped, and others (including stupa-shaped and phra kiao–shaped, depending on the author). [2] [3]
