A lighthouse is a solitary architecture, an object that shows strength, dominance and confidence at daytime, while at night it gives away its majestic presence to the light, emitting its constant eternal signal as far as to the horizon as possible. The importance of lighthouses today decreases due to the mapping of the Seas and the modern navigation systems which allow, in most cases, safe maritine travelling. In the case of the Concordia lighthouse, the function rather turns into a memorial, a striking object in the landscape, a permanent reminder of a disaster. The form of the lighthouse leans on the typical historical lighthouse but the implementation is modern. It stands on a plinth of stone directed to the sea, which is meant to be the meeting point of the youth, a place of silence and meditation. While entering the building and moving upwards, the visitor experiences a gradient change of feelings, from an open vivid space to a room, getting darker and darker. At the end of his way, the visitor enters a dark high space, with no direct contact to the outside; you lose the orientation. The walls are perforated with small openings allowing only dimmed indirect sunlight but no eye contact to the outside. The absence of normal windows, the darkness and the sound of the wind flying through the openings, create a mystic atmosphere, while one could start counting the holes in the wall, just as the souls that have been lost in the seas.
