Flying is the best way to reach the shores of Seoul Ewha University’s new building (founded in 1886, Ewhawelcomes 22.000 female students and is ranked as one of the best universities in the world), thought andrealised by Dominique Perrault, as a result of an international architecture competition organised in 2003,and inaugurated on April 29th 2008.A landscape then, more than an architecture work, located in the midst of Seoul’s university area. Acampus valley where nature, sport grounds, event locations and educational buildings mix, intermingle andfollow one another. A long asphalted strip, delineated at one end by a race track, and completelysurrounded by nature. Arranged nature where pear trees and topiary reign. Black asphalt, red race track,green nature and finally the white brightness of the valley appears. A valley, which is bravely drawn in theground, slides down along a gentle slope. At the other end of the valley, the slope becomes a hugestairway which can be used as an open air amphitheatre if necessary.At the very heart of the valley, a dreamlike immersion takes place. Opposed to the outdoor world, a subtleand serene universe appears suddenly. Classrooms and libraries, amphitheatres and auditoriums, shopsand movement… Everything follows up without any lack of natural light.Perrault is prone to buried, excavated, nestled places (the French National Library in Paris, the Velodromeand Olympic swimming pool in Berlin, both realised, the studies for the Kansai Library in Japan and theCultural Centre in Santiago de Compostela, Spain…) Perrault has the desire, physically speaking, toappropriate the territory, to mingle the construction with the ground, the desire to exploit to its paroxysm theidea that “concept and matter have to grapple one with another”.At Ewha University, Perrault put one more time in action: words (idea, concept, abstraction, geometry,strategy, tension, fusion, freedom, simplicity, evidence…), principles (physics, mechanics, dimension…)and commitments (urban concerns, creation of a location and not only of a building, refusal of formalism,and disappearance of architecture…) which best qualify his architecture.With the inauguration of Seoul Ewha Womans University, Dominique Perrault attests his intenseinternational activity (ME Hotel in Barcelona, achievement in May 2008,the NH-Fieramilano Hotel in Milan,May 2009, the Court of Justice of the European Communities in Luxembourg, December 2008, the TennisStadium in Madrid, May 2009, the DC Towers in Vienna, 2012…).
