This project serves as a memorial to the Lisbon earthquake and tsunami taking place in 1755, in which most of the city was destroyed. The base to our concept is the cracked earth due to the quake and the state of the inundated spaces left behind by the tsunami. By splitting a simple geometric object we are re-animating the catastrophe. The site memorial can be accessed via a slim steel bridge that leads from the shores to the river Tagus. With the grandiosity of blocks and the crack the dramatic effects were made bolder. The visitors arriving into to the crack immediately feel miniscule between the huge blocks whilst facing the depth and hopelessness. The bridge every now and then partially sinks into the waters as the tidal movements are changing. This movement allow us to enter into spaces which are normally under water during high tides.. By playing with simple geometry, the created space with its platicism and the lights entering into the site through the slits trigger depressing feelings, whereas other times causes great reliefs to the visitors. We used local limestones in order to create a stronger bond to the site.
