Sadras is a fortress town located on India's Coromandel Coast in Kanchipuram District, 70 km south of Chennai in Tamil Nadu. Sadras is the anglicized form of the ancient town of Saduranga pattinam.
An inscription found in Sadras dated to 1359 mention this place as Rajanarayanan Pattinam after a Sambuvaraya chieftain. There is a temple to Vishnu here, and because of it later the city was known as Sadiravasagan Pattinam. This later changed into Sadurangapattinam, shortly known as Sadirai. Later the British anglicized it to Sadras.
Modern Sadras was established as part of Dutch Coromandel in the seventeenth century, which was even before center for weaving superfine muslin cloth for export besides Pearl and edible oil. The magnificent Sadras Fort, built for commercial purposes by the Dutch, is a vast compound enclosing a huge granary, stable and structures used to mount elephants; unfortunately only one of these structures survives. The fortress was raided by the British in 1818 and came under the control of the British East India Company. It is now maintained by the Archaeological Survey of India in efforts to contain further dilapidation of this great monument. From 2003 major restoration of the damaged fort was carried out leading to may archeological findings. The first battle between British East India Company and the Dutch started here as Battle of Sadras. The fort contains many beautifully decorated cemetery dated between 1620 and 1769.
