Hôtel Abriot de Grusse

Hôtel Abriot de Grusse is an 18th-century town mansion on Rue Sébile in Lons-le-Saunier, one of the few surviving examples of Louis XVI-style residential architecture in this Jura capital. The building stands on the former site of the Tiercelines convent, and its cellars still incorporate remains of that older monastic structure.

What is the history behind the building?

The hôtel was built at the end of the 18th century as a bourgeois residence in the Louis XVI style — the elegant, symmetrical late-classical idiom typical of the final decades of the French Ancien Régime. During the 19th century the interiors were enriched with further decorative work, a sign that the residence retained its prestige among local notables well beyond its original construction. A turning point came in 1928, when the local Chamber of Commerce moved in, permanently shifting the building's role from private residence to a working public institution.

What can you see inside and outside?

The façades and roof facing Rue Sébile retain their original 18th-century character and are among the main reasons the building earned heritage protection. Inside, the highlights are the grand interior staircase and two first-floor salons, decorated with wood panelling (lambris) and stucco in the classic late-18th-century idiom — decoration counted among the best-preserved interior schemes of the period in the region. The cellars deserve attention too: they hold the oldest, pre-Revolutionary traces of the Tiercelines convent that once stood on this spot before the current hôtel was built.

The building was listed as a monument historique by a decree dated 1 July 1996. The protected elements are specific: the street-facing façades and roof, the interior staircase, the two decorated first-floor salons, and the cellars — in other words, the parts judged most authentic and historically valuable.

How do you get there?

Hôtel Abriot de Grusse stands at 8 Rue Sébile, right in the centre of Lons-le-Saunier, the capital of the Jura department. It sits in the historic heart of town, surrounded by other period townhouses and mansions — a short walk through this district takes you past several comparable examples of 18th- and 19th-century urban architecture.

When is the best time to visit?

Since the building now houses an institution (the Chamber of Commerce), visits are essentially limited to viewing the exterior — best done on a weekday, when the surrounding streets are lively and the façade is easy to appreciate. Lons-le-Saunier is pleasant year-round, but spring and summer are especially good for lingering walks through the historic centre.
