was established by Uugrasena, father of Kansa the then ruler and later Krishna flourished and extended its domain. It is said that Krishna conducted the administration of his kingdom from Dwarka while residing with his family in Bet Dwarka. The city's Dwarkadhish Temple dedicated to Krishna was originally built around 2,500 years ago, but was destroyed by Mahmud Begada rulers and subsequently rebuilt in the 16th century. The temple is also the location of Dwaraka maţha, also called Sharada Matha/Peeth and "western peeth", one of the four peeths (Sanskrit: "religious center") established by Adi Shankaracharya. As an important pilgrimage centre for Hindus, Dwarka has several notable temples, including Rukmini Devi Temple, Gomti Ghat, and Bet Dwarka. There is also a lighthouse at the land end point of Dwarka. Archaeology Archaeological investigations at Dwarka, both on shore and offshore in the Arabian Sea, have been performed by the Archaeological Survey of India. The first investigations carried out on land in 1963 revealed many artefacts. Excavations done at two sites on the seaward side of Dwarka brought to light submerged settlements, a large stone-built jetty, and triangular stone anchors with three holes. The settlements are in the form of exterior and interior walls, and fort bastions. From the typological classification of the anchors it is inferred that Dwarka had flourished as a port during the period of the Middle kingdoms of India. Coastal erosion was probably the cause of the destruction of what was an ancient port. Dwarka is mentioned in the copper inscription dated 574 AD of Simhaditya, the Maitraka dynasty minister of Vallabhi. He was the son of Varahdas, the king of Dwarka. The nearby Bet Dwarka island is a religious pilgrimage site and an important archaeological site of the Late Harappan period, with one thermoluminescence date of 1570 BC. Early history An epigraphic reference ascribed to Garulaka Simhaditya, the son of Varahdas, the king of Dwarka, is inscribed on a copper plate dated to 574 AD, found in Palitana. The Greek writer of the Periplus of the Erythraean Sea referred to a place called Baraca, which has been interpreted as present-day Dwarka. A reference made in Ptolemy's Geography identified Barake as an island in the Gulf of Kanthils, which has also been inferred to mean Dwarka. One of the four dhams (religious seats), which were founded by Adi Shankaracharya (686–717 AD) at the four corners of the country, was
