Oxford's unique architecture spans centuries and ranges from Gothic to neo-classical to post-modern. As a destination, it draws visitors worldwide and serves as a draw for many of its students. As Oxford puts it, "Oxford is famous for its historic buildings, which attract millions of tourists every year, and perhaps less well known for the cutting-edge design of our most recent buildings. Conservation and excellence in design are central to our work, in order to preserve and develop the University's estate and ensure that we provide world-leading teaching and research facilities for our staff and students. The University's buildings and estate are not only necessary for our academic work; they also contribute to Oxford's reputation as a city of learning, heritage and culture. They form a vital part of the rich architecture of the city and provide a beautiful environment for visitors and Oxford residents, as well as University staff and students."
