Billy: Fortress and Historic Buildings

Billy offers two clearly distinct focuses for planning a trip: the medieval fortress and historic buildings, and routes that take in local history or the landscape. The buildings date from the late 12th to the 16th century; their functions include fortification, residence and the administration of justice. There is also a Romanesque crypt and a variety of routes. When choosing Billy as a destination for your stay, you can decide whether to focus primarily on architecture, religious heritage or routes.

Fortress and Historic Buildings

The Forteresse de Billy dates from the late 12th and early 13th centuries. It stands on a circular hill about 50 metres above ground level. The Tour Barbery was part of the fortress’s second fortified enclosure, which consisted of seven towers connected by defensive walls.

Another defensive structure was the Porte Chabotin: it protected the first level of fortifications and had a passage with a portcullis, a murder hole and loopholes. A portcullis is a gate that can be lowered; the murder hole and loopholes were other structural elements of the defences. Together with the Tour Barbery, these structures illustrate different parts of the fortifications, whose functions should not be conflated.

The Capitainerie was built in the 14th century at the entrance to the outer bailey and served as the residence of the fortress captain. The captain administered justice in the Auditoire. Today, the building houses the tourist office, an exhibition room and the post office. The former residential and judicial functions can thus be associated with two named buildings, while the Auditoire also has present-day uses.

The houses also contribute to the area’s architectural history. The Maison du Marchand, or Merchant’s House, is a half-timbered house dating from the 15th century. The Maison protestante is a Renaissance residence from the 16th century. The Église Saint-Cyr-Sainte-Julitte preserves another layer of history in its 11th-century Romanesque crypt: known as the Cave Saint-Georges, it is open to visitors. Your sightseeing options therefore include both dated buildings and an interior space explicitly open to visitors.

Planning Routes and Experiences

The routes differ in length, course and explicitly stated accessibility. The 22-kilometre Boucle des Patrimoines passes by the fortress and the Église Saint-Cyr-Sainte-Julitte via a variant. Hiking trail PR No. 51, Le sentier du Renard, takes in Billy’s medieval history and runs through fields and hamlets, over slopes and along the banks of the Allier. The Via Allier stretches 27 kilometres between Billy and Saint-Yorre and is accessible to pedestrians and cyclists. These details can help you compare the named routes by their course and the options described; no walking time is specified.

The tourist office offers seasonal guided tours of the Forteresse de Billy: Wednesday to Sunday in April, May, June and September, at 2 pm and 4 pm. As seasonal schedules can change, check the latest information before your visit. Billy also offers a large-scale escape game throughout the village; check availability in advance. La Marche des remparts is an event held in April. If it is important to your travel plans, ask about the specific dates rather than assuming it takes place every year.

During a stay in Billy, you can weigh up medieval fortress architecture, houses from different centuries, the accessible crypt and a range of routes. The Forteresse combines early military history with seasonal guided tours, while the routes offer different focuses in terms of distance, scenery and access for pedestrians or cyclists. Check the latest information about date-specific offerings before your trip.
