 LSE operates the George IV public house and the students' union operates the Three Tuns bar.The School's campus is noted for its numerous public art installations which include Richard Wilson's "Square the Block", Michael Brown's "Blue Rain", Christopher Le Brun's "Desert Window".Since the early 2000s, the entire campus has undergone an extensive refurbishment project and a major fund-raising "Campaign for LSE" raised over £100 million in what was one of the largest university fund-raising exercises outside North America.
