A bishop's fortress on a Savoy plan

Built like Savoy, held against it

A castle raised by the bishops of Lausanne stood 300 feet from where you are, in a town that never once belonged to Savoy.

The short answer

19 Chemin de Bouleyres in Bulle, Switzerland lies some 300 feet from the Castle of the bishops of Lausanne, built between 1291 and 1331 on a Savoy-style square plan even though Bulle itself never belonged to Savoy. The castle later served as bailiff's residence, prefecture, and from 1854 a canton prison.

1291 to 1331

Bishops built a Savoy-plan tower to hold Bulle

The Castle of the bishops of Lausanne, then baillivale residence and prefecture went up on the south side of Bulle's market place between 1291 and 1331. The bishops of Lausanne built it, and they built it strange. Its square plan had corner towers and a central courtyard. This was the signature of the House of Savoy. It was stamped across castles in nearby Vaud at Morges, Romont, and Yverdon-les-Bains. But Bulle was never Savoy ground. It stayed an episcopal town. The bishop's own castellan and mayor ruled it. Meanwhile Lausanne and Savoy fought bitterly over who got to sit in the bishop's chair. That fight had only just gone the bishop's way when the castle was raised. A Savoy coat of arms turned up carved into one of its windows during a later renovation. It looks like a short window, sometime before 1239, when a Savoy bishop briefly held Lausanne and may have left a building behind him. Whatever its first owner intended, the finished tower rose thirty-three meters over the town's south gate. It dominated the plain below and it was built to keep Bulle in the bishop's hands, not to give it away.

The castle was built to a Savoy plan in a town that was never Savoy's.
1476 to 1536

A fleeing bishop lost the castle for good

The castle survived its first real test without a fight. When the Swiss confederacy crushed Burgundian Wars forces at the Battle of Morat in 1476, Bulle avoided the looting that followed. It had allied itself with Fribourg months earlier. The bishop's fortress stood untouched. Sixty years later the ground shifted for good. In 1536 the Bernese conquered the Vaud. Sébastien de Montfalcon, the bishop of Lausanne, fled the region entirely. He never came back to reclaim what he had left standing. Fribourg used his absence to fold Bulle under its own protection. Then it quietly turned the bishop's castle into a bailiff's seat. An agreement with the bishop of Lausanne in 1614 made the arrangement formal. But the change had already happened in the moment he ran. The castle had been built to hold the town for its bishop. Now it held it for someone else. The man it was taken from never set foot in it again.

1418 and before

One family ran the castle behind the bishop's name

The castle's authority had already been quietly captured long before any bishop fled it. Antoine de Challant, a Savoyard cleric, died at Bulle in 1418, decades into the bishops' rule from the fortress on the square. By then the office of mayor, the bishop's own appointee, had stopped moving between families. For generations the noble de Bulle family held it, passing it down as if it were theirs by blood rather than the bishop's gift. The bishop still named the castellan. He still called himself lord of the town. But the daily running of Bulle sat with one family, entrenched inside the bishop's own administration. Nobody drove them out and nobody needed to. The office simply stayed put, year after year, until holding it looked the same as owning it.

The castle would change hands again, and this time the town itself did the taking.
1798

Townspeople expelled the governor and took the seat

French revolutionary armies were pushing into Switzerland when the people of Bulle moved first. The governor still sat inside the old bishop's castle, by then a bailiff's seat under Fribourg for over two centuries. In 1798, with the old order collapsing around them, the townspeople expelled him themselves. No outside force did it for them. They simply walked in and took the seat of power while everyone with a claim to it was looking elsewhere. The castle that had passed from bishop to Fribourg by way of one man's flight now changed hands again. This time the town itself took it. The town it had always stood over.

2 April 1805

Fire swept the town but spared the castle

Seven years later, fire did what soldiers and revolutions had not. On 2 April 1805, flames tore through Bulle. Wooden roof tiles caught fire and carried it from house to house across the whole town. The Castle of the bishops of Lausanne, then baillivale residence and prefecture still stood on the market square, close by. Rebuilding took half a century. The town that rose from the ash had the money to rebuild it. The town had the will to rebuild it. No old authority came back to claim it. The fire didn't care who was supposed to be in charge. Neither did the town afterward.

Nobody who built this town ever handed it back to whoever built it first.
1854 to now

The bishops' fortress became a canton prison

By 1854 the castle had been a bailiff's seat for over three centuries, and Fribourg made the arrangement permanent. Prison cells went into the old fortress that year. The bishops of Lausanne had raised this stone as a symbol of their own hold on the town. Now it held prisoners for a canton. The castle still stands on the market place, 300 feet from where you are. Its Savoy-plan towers have not changed since the fourteenth century.

The tower the bishops raised to hold the town still stands over the market place, held now by whoever came after them.
