The Fort du Portalet is a fort in the Aspe Valley in French Pyrenees, built from 1842 to 1870. The fort, built by order of Louis Philippe I, guards the border of the Pyrenees and protects access to the Col du Somport. Fort du Portalet is located on a cliff face underneath the Chemin de la Mâture and overlooks the torrential river Gave d'Aspe. Begun in 1842 and finished in 1870, the fort replaced an earlier structure further north.
Capable of accommodating 400 men, the fort served as depot and barracks for the 18th Regiment of Infantry between 1871 and 1925. It then ceased to be used as a full-time military facility.
During World War II, the Vichy regime arrested and interned Léon Blum, Édouard Daladier, Paul Reynaud, Georges Mandel and Maurice Gamelin as political prisoners at the fort. After the Riom Trials, Reynaud was transferred to German custody and held in Germany. Mandel was taken to Paris, where he was executed in 1944 by the Milice in retaliation for the assassination earlier that year of Philippe Henriot, a Vichy official, by the Resistance. After the war, Philippe Pétain, the head of the Vichy government, was imprisoned in the fort from 15 August to 16 November 1945.
After the government abandoned the fort, it was bought by the local authorities in 1999. They are restoring it.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
