A hidden space is located at Taşkışla ITÜ campus. The atmosphere of the unknown space is described as a calm, silent and cool one. Associations coming up are a gap, void, separation. Its use is on the one hand to supply class rooms with light, on the other hand also creating space for technology, ventilators, tubes and electricity. A treasure hunt is created that should inspire to explore and experience the space. Two surprises as rewards are designed: an oasis of tranquility, as a space of silence, cleansing, as well as vitalization. An assembly hall, a space of democracy, symbolizing the parliament of Ancient Greek as a place of exchange, the archetype of interaction.
