The newest major structure on site, the Feynman Computing Center, is a three-story semicircular structure of 74,000 square feet which houses the central computing facilities for the Laboratory. The building's pre-cast concrete backbones are supported on a steel frame, as is the north-facing glass facade. The pre-cast panels provide protection from the sun's heat and also duplicate the vertical lines of Ramsey Auditorium to the south.
The Fermilab Village, once the village of Weston, lies on the eastern boundary of site. The entire village was continued within the land purchased by the State of Illinois in the late l960s and donated to the federal government for the construction of Fermilab. Many of the village houses now serve as residences for visiting scientists while others are utilized as small, self-contained laboratories.
A number of the original farm homes on the site were moved to form an additional housing complex adjoining the village.
Other architectural landmarks include a concrete Archimedes Spiral covering the pumping stations at Casey's Pond and a distinctive series of high voltage transmission lines which resemble the Greek letter pi (n).
