 Seventeen sites were registered in 1944 as "Horizons Palois", in order to protect them from any construction or alteration that may deteriorate the extraordinary panorama which is particularly visible from the Boulevard des Pyrénées and the château.The city of Pau has committed several years of reflection to a candidacy of the Horizons to UNESCO World Heritage.This would thus enhance the protection of the panorama, and also be an improvement with the renaming of this site to the general public.
