The Indian Institute of Technology, Madras, is an autonomous statutory organization functioning within the Institute of Technology Act. IIT Madras offers undergraduate, postgraduate and research degrees across 15 disciplines in Engineering, Sciences, Humanities and Management. About 360 faculty belonging to science and engineering departments and centres of the Institute are engaged in teaching, research and industrial consultancy. Founded in 1959 with technical and financial assistance from the government of the former West Germany, it is third among the Indian Institutes of Technology established by the Government of India. The campus is spread over 250 hectares of lush green forest. The Institute in itself is located around 2.5 km inside the campus. There are schools, banks, shopping malls, temples and churches inside the campus. Much of the campus is a protected forest, carved out of the Guindy National Park, home to chital (spotted deer), black buck, and other wildlife. A natural lake, deepened in 1988 and 2003, drains most of its rainwater.
