2 Best Sights in The Basque Country, Gascony, and Hautes-Pyrenees, France

There are splendid views of the peaks of the Pyrénées all the way along this promenade, just under a mile long, which extends from the Château to the Palais Beaumont. A free funicular, with its top station in the middle of the boulevard, connects the city center with the railroad station beneath.

Several sights of interest line Rue de la Citadelle, including the Maison Arcanzola (Arcanzola House) at No. 32 (1510), the Maison des Évêques (Bishops' House) at No. 39, and the famous Prison des Évêques (Bishops' Prison) next door to it. Continuing up you'll reach the Citadelle itself—a classic Vauban fortress built between 1625 and 1627, now occupied by a school. The views from the top, complete with maps identifying the surrounding heights and valleys, are panoramic.
