Ignasi de Solà Morales

Ignasi de Solà-Morales Rubió (Barcelona 1942 - Amsterdam 2001) was a Catalan architect, historian and philosopher.

He was professor of composition at the Barcelona School of Architecture, and also taught at the universities of Princeton, Columbia, Turin, and Cambridge.

Among his most notable architectural works are the reconstruction of Ludwig Mies van der Rohe's Barcelona Pavilion, and the reconstruction and expansion of the Liceu Theatre in Barcelona.

Ignasi de Solà-Morales has coined the term "terrain vague", applied to abandoned, obsolete and unproductive areas, with no clear definitions and limits.
