Some of the earliest surviving grand Vishnu temples in India have been dated to the Gupta Empire period.
The Sarvatobhadra temple in Jhansi, Uttar Pradesh, for example, is dated to the early 6th century and features the ten avatars of Vishnu.
Its design based on a square layout and Vishnu iconography broadly follows the 1st millennium Hindu texts on architecture and construction such as the Brihat Samhita and Visnudharmottarapurana.

Archaeological evidence suggest that Vishnu temples and iconography probably were already in existence by the 1st century BCE.
The most significant Vishnu-related epigraphy and archaeological remains are the two 1st century BCE inscriptions in Rajasthan which refer to temples of Sankarshana and Vasudeva, the Besnagar Garuda column of 100 BCE which mentions a Bhagavata temple, another inscription in Naneghat cave in Maharashtra by a Queen Naganika that also mentions Sankarshana, Vasudeva along with other major Hindu deities and several discoveries in Mathura relating to Vishnu, all dated to about the start of the common era.

The Padmanabhaswamy Temple in Thiruvananthapuram, Kerala, is dedicated to Vishnu.
The temple has attracted huge donations in gold and precious stones over its long history.
