of Egg. The university's botanical garden is located to the north-west of the north parking lot and is open on weekdays. Before the independent village of Allmannsdorf was merged with the city of Konstanz on 1 January 1915, all of the land that the university now occupies belonged to this former community. Architecture The university was designed as a customised space to facilitate social interaction between researchers, teachers and students, thereby departing from traditional university building layouts. Instead of a scattered array of individual buildings, architect Horst Linde drafted a compact university complex with interlinked buildings. The idea was to adapt the architecture to the hillside location, similar to a mountain village. Designer Wilhelm von Wolff's idea was that "people should be able to stroll through the university as if it were an old city centre with squares and alleyways that provide opportunities for casual encounters, perhaps with something mysterious here and there to rouse expectations". In order to shorten the routes to the centrally-located Agora, the planners made it a requirement that the radius of the university area should not exceed 500 to 700 metres. Construction started in 1970 and lasted until 1983. Since then, the university has made several additions, all of which followed the original plans. In 2012, major university building sections were identified as historic monuments and provided official monument protection in recognition of their collective design and construction. Percent for art The following artworks have been constructed as part of Percent for art projects on university grounds: The glass roof (1972) consisting of 227 coloured pyramids in the main entrance area of the university, designed by Otto Piene; the pipe sculptures (1969–1974) by Friedrich Gräsel in the Hockgrabental; the gate structures (1984) by Georg Karl Pfahler; the spool sculpture (1972) by Gottfried Bechtold; and the wooden head sculptures (1993) by Stephan Balkenhols.
