Colombier Castle

Colombier Castle (Château de Colombier) rises in the village of Colombier in the Swiss canton of Neuchâtel, close to the shore of Lake Neuchâtel. It is a heritage site of national significance, and it has served the army for more than two centuries. Beneath it lie the remains of one of the largest Roman villas found in Switzerland.

What is this place and where does it come from?

The oldest chapter is Roman. Between 1840 and 1842, Frédéric DuBois de Montperreux uncovered the ruins of a sprawling villa under the site, among the biggest of their kind in the country. A fortified tower went up over those remains in the 11th or 12th century. The complex grew in the 13th century and, by the 16th, had taken on the layout still recognisable today: a compact block around a courtyard.

Why does the army own it?

In 1806 the castle became a military hospital. From 1824 federal militias used it as a drill ground, and later it turned into barracks with an enlarged arsenal. Neuchâtel joined the Swiss Confederation in 1815 but only shook off Prussian oversight in 1857, so Colombier's federal role belongs to a fairly late stage of the canton's story. Today the Swiss military owns the site and training bodies operate here, among them the infantry school.

What can you see?

The main draw is the architecture itself: heavy walls, the courtyard and the setting beside an old wine-growing village. Part of the complex has housed the Musée militaire, and the castle has also shown work by the Art Nouveau painter Charles L'Eplattenier (1874-1946). Because this is a working military site, access and museum hours change, so check the current situation with the Milvignes municipality or the museum before you go.

How do you get to Colombier?

The village sits a few kilometres west of Neuchâtel, on the lakeside railway line and on the suburban route running from Neuchâtel towards Boudry. From central Neuchâtel the trip by train or local transport takes about a quarter of an hour. By car, leave the A5 motorway that follows the lake. The castle stands near the village centre, an easy walk from the station.

When should you visit?

Late spring and early autumn work best, when the castle pairs naturally with a stroll along the lake and through the vineyards of the Three Lakes region. It fits a day-trip itinerary of nearby fortifications, for example neighbouring Boudry.

Frequently asked questions

Is Colombier Castle open to visitors?

It is a military site, so access can be limited. Confirm current visiting arrangements with the Milvignes municipality or the Musée militaire before travelling.

What lies beneath the castle?

The ruins of a Roman villa, excavated in 1840-1842, counted among the largest Roman residences known in Switzerland.

When was the castle built?

The tower dates from the 11th or 12th century, it was extended in the 13th, and the building reached its present form in the 16th century.

Is it the same castle as the one in Boudry?

No. Boudry is nearby and has its own fortress, but Colombier is a separate castle with its own military history.
