The Administration group of buildings are situated on a tract of land 110 acres in extent and were held
under lease from the University Corporation by the Exposition Company since January, 1902. The University
took back the Fair's leased land after January, 1905.
The Fair commission initially looked into utilizing land a block away from riverfront land, but after citizen did not
desire this, the company looked at Forest Park.
The leasing fee totaled 1,378,000 dollars. This allowed the FairCompany to utilize 1,240 acres for the Exposition.
The Exposition Company used the University's ten buildingsfor administration and other purposes. The principal building-
University Hall (now known as Brookings Hall), is a quadrangular built of red Missouri granite, laid in broken range rubble, with quoins and ornamental courses of cut stone. It stands facing due east, opposite Administration Avenue, which is the extension of Lindell Boulevard. it contains a Tudor-like 77-foot tower, with four-cornered towers surmounting the arched doorway. This doorway is 25 by 38 feet. A terrace of cut stone, 50 feet wide and 264 feet long, rises to the arched entrance from the level of Administration Avenue.
Busch Hall, the two Cupples Halls and Liggett Hall, smaller in stature were built of the same material and in the same style.
An additional 100,000 dollars rent was paid to Washington University by the Exposition Company when the Fair was delayed to 1904. The funds were used to build additional facilities for the Fair and University.
The Administration Building was the official reception hall used to meet dignitaries and other Fair-going VIPs. It also served as an exhibit of a model university.
