A Jain temple or Derasar is the place of worship for Jains, the followers of Jainism. Jain architecture is essentially restricted to temples and monasteries, and secular Jain buildings generally reflect the prevailing style of the place and time they were built.

Jain temple architecture is generally close to Hindu temple architecture, and in ancient times Buddhist architecture. Normally the same builders and carvers worked for all religions, and regional and period styles are generally similar. For over 1,000 years the basic layout of a Hindu or most Jain temples has consisted of a small garbhagriha or sanctuary for the main murti or cult images, over which the high superstructure rises, then one or more larger mandapa halls.

Māru-Gurjara architecture or the "Solanki style" is, a particular temple style from Gujarat and Rajasthan (both regions with a strong Jain presence) that originated in both Hindu and Jain temples around 1000, but became enduringly popular with Jain patrons. It has remained in use, in somewhat modified form, to the present day, indeed also becoming popular again for some Hindu temples in the last century. The style is seen in the groups of pilgrimage temples at Dilwara on Mount Abu, Taranga, Girnar and Palitana.

In 2016, Archaeological Survey of India (ASI) excavated another 13 ft (4.0 m) statue of Bahubali made in the 3rd – 9th centuries on another hillock located opposite the basadis in Arthipura. Excavation work is expected to be completed by 2018.
