The University of Delhi is the premier university of the country and is known for its high standards in teaching and research and attracts eminent scholars to its faculty. The University of Delhi was established in 1922 as a unitary, teaching and residential university by an Act of the then Central Legislative Assembly. Only three colleges existed then in Delhi: St. Stephens College founded in 1881, Hindu College founded in 1899 and Ramjas College founded in 1917, which were affiliated to the University. The University thus had a modest beginning with just three colleges, two faculties (Arts and Science) and about 750 students. In October 1933, the University offices and the Library shifted to the Viceregal Lodge Estate, and till today this site is the nucleus of the University (Main Campus). Apart from central administrative offices, examination offices and the sports complex, the main departments of the Faculty of Science are housed in the Viceregal Lodge Estate.
