As it stood in 1475

What Grandson Castle looked like in its prime.

A compact medieval stone fortress of pale local masonry with continuous high curtain walls punctuated by multiple towers and a clear roofline of the residential ranges; the château stands on the low plain beside Lake Neuchâtel so its southeastern wall originally met the water. Battlemented wall-walks run along the ramparts; the northern wall shows vestigial masonry where a dungeon tower once stood, and a later western extension is built over earlier foundations.

Its story

The story of Grandson Castle.

The Lords of Grandson are first mentioned in the second half of the 11th century, when the castle was built. The house sired a number of powerful scions, including bishops of Basel, Lausanne, Toul and Verdun, and as the lords expanded their power they came repeatedly into conflict with the nearby monastery of Romainmôtier. Otto I is the most famous of the line; after his death in 1328 his brother William moved to England, where he founded the line of the Lords of Grandisson.

The main line remained close to the House of Savoy and possessed the confidence of the Count, but declined from the end of the 14th century. Otto III was accused of having killed Amadeus VII, Count of Savoy, in a fight, and John II of Grandson was convicted of forgery and sedition against the Duke of Burgundy and sentenced to death by suffocation. When John II died, the power of the family died with him.

Rebuilt in the 13th century, the castle played its part in the Burgundian Wars of the 15th century, very few of Charles's soldiers were killed, but the Swiss had humiliated the greatest duke in Europe, defeated one of the most feared armies and taken a most impressive amount of treasure. The fortress survives largely complete, one of the best-preserved medieval castles in Switzerland and a heritage site of national significance.
