Mandapa (Sanskrit: मण्डप, Hindi: मंडप, Marathi: मांडव; also spelled mantapa or mandapam) in Indian architecture is a pillared outdoor hall or pavilion for public rituals.
In the Hindu temple the mandapa is a porch-like structure through the (gopuram) (ornate gateway) and leading to the temple. It is used for religious dancing and music and is part of the basic temple compound. The prayer hall was generally built in front of the temple's sanctum sanctorum (garbhagriha). A large temple would have many mandapas.
If a temple has more than one mandapa, each one is allocated for a different function and given a name to reflect its use. For example, a mandapa dedicated to divine marriage is referred to as a kalyana mandapa. Often the hall was pillared and the pillars adorned with intricate carvings. In contemporary terms, it also represents a structure within which a Hindu wedding is performed. The Bride & Groom encircle a holy fire lit by the officiating priest in the center of the Mandapa.
When a temple has more than one mandapa, they are given different names.
In Indonesia, the mandap is known as a pendopo. Unusually, Indonesian pendopos are built mostly for Muslim communities. Many mosques follow the pendopo design, with a layered roof to resemble Mount Meru.
In Tamil, this platform is the Aayiram Kaal Mandapam – a distinctly thousand pillared hall close to the vimana of the Koil which forms a distinct part of the site plan of classical Dravidian architecture.
