The delicate setting where the castle of Roccascalegna stands makes any intervention to be intrusive per se. In order to mitigate the impact on an architecturally unique landscape, the proposal was divided into three parts. While the Observatory Houses follow the spine of the cliff, the Observatory Centre raises between the trees at the foot of the castle. The circular shape of the building dialogues with the crescent and the sky, creating an observation platform above the forest. The third intervention consists of seven micro-observatories placed inside the walls of the castle. The scale of the intervention demanded a brave but respectful approach that could dialogue both with the past and present.
