Hôtel du Bas du Gast

Hôtel du Bas du Gast is an 18th-century private mansion in Laval, in the Mayenne department of France, registered as a historic monument. It stands on rue de la Halle-aux-Toiles, right at the foot of the former Place du Gast, and ranks among the finest examples of secular architecture in the old town of Laval.

What does the name mean, and who built it?

Despite the word "hôtel" in its name, this is not a place to book a room — in French, a "hôtel particulier" simply means a grand townhouse. The building was erected in 1742 for Michel-Jean du Mans du Chalais, receiver of the salt granaries of Laval, on the site of the earlier Hôtel Marest. His role overseeing the "grenier à sel" — the state-controlled municipal salt store — explains why the residence was built on such an ambitious scale. It was enlarged in 1762, and the interior decoration was completed in 1773, giving the house a coherent, mature character typical of the period.

What makes the architecture worth a look?

The mansion is built around a U-shaped plan, with outbuildings framing a courtyard, and gardens have surrounded it since the outset — a layout that has survived largely intact since the 18th century despite later alterations. The façade's triangular pediment carries a carved motif of two doves flanking a basket of flowers, a symbol of love and purity commonly used in residential decoration of the era. Inside, the woodwork and paneling are of notably high quality, with further wood paneling added in the second half of the 18th century, making the interior one of the region's better-preserved examples of upper-bourgeois decor.

What about the gardens?

The gardens are one of the property's main draws. In the 1920s, two contrasting gardens were laid out: the lower part of the grounds became a picturesque English-style landscape garden, still holding the remains of an ornamental folly, while the area in front of the house was shaped into a formal French garden built around symmetrically clipped, cone-shaped boxwood. The pairing of the loose English layout with the geometric precision of the French garden reflects the tastes that shaped country and townhouse gardens in that period.

Is the mansion protected, and can visitors go inside?

The property was listed in the inventory of historic monuments by a decree dated 10 June 1997. It remains a private residence today, so access to the interior is not open to the general public. The garden and exterior spaces, however, are sometimes opened to visitors during the European Heritage Days (Journées européennes du patrimoine), when Laval opens up several of its most valuable townhouses to the public — the best chance to see the pediment up close and walk through both gardens.

How do you get there, and what else is nearby?

The mansion sits in the historic center of Laval, near the site of the former cloth market hall (halle aux toiles), which gives the street its name. From there it's an easy walk to Laval Castle and the banks of the Mayenne river, making it simple to combine a visit to the Bas du Gast with a broader stroll through the old town.

Frequently Asked Questions

Is Hôtel du Bas du Gast a hotel where you can stay overnight? No. Despite the name, it is a historic private mansion, not an accommodation. "Hôtel" here reflects the older French sense of the word — a grand urban residence — rather than a modern hotel.

When is the best time to visit? The most reliable window is during the European Heritage Days in September, when the building and gardens are sometimes opened to the public; outside that period, access is limited since the property remains privately occupied.

What's the main highlight of the site? The combination of 18th-century architecture with two contrasting historic gardens — English and French, both laid out in the 1920s — along with the façade's carved dove-and-flower-basket motif.

Since when has the building been legally protected? It has been listed on the register of historic monuments since 10 June 1997, confirming its recognized value within France's architectural heritage.
