Château de Betz

Château de Betz is a medieval stronghold standing in the commune of Betz-le-Château, right by the locality of Le Tivoli, in the Indre-et-Loire department of France's Touraine region. The castle blends the remains of an early medieval earthwork motte with a stone structure raised centuries later, making it one of the more interesting fortified sites in the Loire Valley.

How did the castle come to be?

The site's history goes back to Carolingian times, when a defended settlement with an earthen motte already stood here. The first recorded lord of Betz was Gilles de Betz, who around the year 1000 obtained permission from Fulk Nerra, Count of Anjou, to replace the earlier timber defences with a stone stronghold. The layout visitors see today, though, dates from much later: Pierre de Betz and his wife Catherine de La Jaille rebuilt the residence between 1444 and 1476, giving it the form that has survived to the present.

What is there to see on site?

The most recognisable feature is the round tower, whose core was built in the 12th century on foundations that are even older, dating to the 11th century. The main building has a quadrangular eastern section flanked by that cylindrical tower and other turrets, including a square keep at the north-eastern corner. This mix of building styles from several different eras makes it possible to trace how fortification techniques evolved here over time.

What is hidden underground?

Beneath the château runs a network of underground passages stretching several dozen metres, likely older than the stone castle itself and possibly dating to the 11th century or earlier. These were not simple connecting tunnels but refuge shelters: in the event of an attack they could hide several dozen people at once, and a natural spring inside meant occupants could survive there for several days if needed. The passages were opened to the public after trial visits in 2020, with regular tours starting in July 2021 once safety and restoration work had been completed.

When and how can you visit?

Tours of the underground passages run mainly in the afternoons during July and August, and booking ahead is strongly advised since each group is limited in size. The entry ticket covers the underground tour and also includes free access to the castle grounds plus the chance to climb to the top of the tower, which offers a view over the surrounding Touraine countryside.

Why is it worth a visit?

Betz-le-Château brings together several layers of history in one spot: a Carolingian defensive settlement, a medieval tower, and a later reconstruction into a noble residence. It is unusual to find both above-ground defensive architecture and genuine, centuries-old underground shelters open in the same location, especially since the tunnels were inaccessible to visitors until quite recently. The site appeals equally to architecture enthusiasts and to travellers hunting for lesser-known, unpolished Loire Valley landmarks away from the busiest tourist routes.
