Conversion of non-Hindu places of worship into temples

The conversion of non-Hindu places of worship into temples occurred for centuries, ever since the advent of other Dharmic faiths in the Indian subcontinent. As a result, Muslim mosques, Christian churches, Zoroastrian fire temples, Jain and Buddhist temples were converted into Hindu places of worship. Since the dawn of the 20th century, there have been active movements to convert non-Hindu religious sites into temples, primarily in the West and in India.

This table lists former mosques which were built by destroying Hindu temples on sites of religious significance that have now been reclaimed and converted back into Hindu Temples.

This table lists former Churches with identified original buildings that have been converted into Hindu Temples. It only includes those Churches where the original structure was never a site of a temple.

A Hindu sect, known as Swaminarayan Gadi Sansthan, has been buying former churches and converting them into temples, in the US and the UK. The sect is headquartered in Maninagar, Ahmedabad. In India, however, the conversion of Churches to temples is more violent.
