The city is located in the heart of the former sovereign principality of Béarn, of which it was the capital from 1464. Pau lies on the Gave de Pau, and is located 100 kilometres from the Atlantic Ocean and 50 kilometres from Spain. This position gives it a striking panorama across the mountain range of the Pyrenees, especially from its landmark "Boulevard des Pyrénées", as well as the hillsides of Jurançon. According to Alphonse de Lamartine, "Pau has the world's most beautiful view of the earth just as Naples has the most beautiful view of the sea."
