Angkor Wat is a temple complex at Angkor, Cambodia. It is the largest religious monument in the world, on a site measuring 162.6 hectares (1,626,000 m2; 402 acres) which was built by a Khmer king Suryavarman II in the early 12th century as his state temple and capital city. As the best-preserved temple at the site, it is the only one to have remained a significant religious center since its foundation — first Hindu, dedicated to the god Shri Vishnu.
The Srirangam Temple is often listed as the largest functioning Hindu temple in the world. The temple, located in Tamil Nadu, occupies an area of 156 acres (631,000 m²) with a perimeter of 4,116m (10,710 feet), making it the largest temple in India and one of the largest religious complexes in the world. The temple is enclosed by seven concentric walls (termed prakarams (outer courtyard) or mathil suvar) with a total length of 32,592 feet or over six miles. These walls are enclosed by 21 Gopurams. The Ranganathanswamy Temple complex with 49 shrines, all dedicated to Lord Vishnu, is so huge that it is like a city within itself. However, the entire temple is not used for the religious purpose, the first three out of seven concentric walls are used by private commercial establishments such as restaurants, hotels, flower market, and residential homes.Taking this detail into account, still the temple ranks third to in the list of large Hindu temples after Thillai Nataraja Temple, Chidambaram and TiruvannamalaiAnnamalaiyar Temple. The temple was awarded with UNESCO Asia Pacific Award for Cultural Heritage Conservation Program in the year 2017 for the category ‘Award of Merit’.
The Chhatarpur Temple was established in 1974, by Baba Sant Nagpal ji, who died in 1998. His samadhi shrine lies in the premises of the Shiv-Gauri Nageshwar Mandir within the temple complex. This temple was considered as the biggest temple in India and second largest in the world, before the Akshardham Temple was created in 2005 in Delhi. This temple is totally constructed from marble and on all the facets there is jaali (perforated stone or latticed screen) work. It can be classified a vesara style of architecture.
