Mandapa

[3] The prayer hall was generally built in front of the temple's sanctum sanctorum (garbhagriha).

The bride and groom encircle a holy fire lit by the officiating priest in the center of the mandapa.

[4][7] In Burmese, the term mandat (မဏ္ဍပ်), which has etymological origins in Pali maṇḍapa, is an open platform or pavilion from which people spray water to passers-by during the Buddhist festival Thingyan.

Khmer people often refer it as a small shrine with high crown-shaped like tower, decorated with exquisite ornaments in various styles.

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.

Open mandapa with pillars and courtyard.
