The Société des Autoroutes de France presented
the Taller de Arquitectura with a very imprecise brief for the design of a
park. Given the aggression the mountain had suffered as a result of having to
accommodate a motorway, and the unappealing nature of this kind of public work,
it was decided to build a monument to dignify the new highway and to recall the
importance of the Pyrenean passes in the history of Catalonia. The pyramid,
built from the stones excavated while the motorway was under construction, sits
on an 80-m high 100 x 100-m square base. The garden that surmounts it creates a
false perspective that highlights the temple on the top, a monument in homage
to Catalonia. Its red brick columns represent the four stripes on the Catalan
flag.
