The Indian Institute of Technology Bombay (abbreviated IITB or IIT Bombay) is a public engineering institution located at Powai, Mumbai, India. It is the second-oldest (after Indian Institute of Technology Kharagpur) institute of the Indian Institutes of Technology system. IIT Bombay was founded in 1958. In 1961, the Parliament decreed IITs as Institutes of National Importance. A high-power committee of Government of India recommended in 1946 establishment of four higher institutes of technology to set the direction for the development of technical education in the country. Planning for the Institute at Mumbai began in 1957 and the first batch of 100 students was admitted in 1958. Since its establishment in Powai, the institute has physically expanded to include more than 584 major buildings with a combined area of more than 2.396 gross square feet (550 acres or 2.22 km²).
