The Hôtel du Croissant was built in the 16th or 17th century as a post station on the road from Paris to Beauvais. Its round-arched portal opens onto a courtyard lined by four buildings that served as an inn for travellers, a stable for the horses and a coach house for the mail coaches. The building on Rue Basse-de-la-Vallée No. 2 has been a protected monument historique since 1984.

The building's name comes from the crescent, French croissant, a sign once hung outside coaching inns to show travellers that a post relay was open. The Hôtel du Croissant served riders and horses on the Paris–Beauvais road, with a courtyard ringed by four buildings: lodging, stables and a coach house.

The building stands at No. 2 Rue Basse-de-la-Vallée, and its arched portal opens onto a courtyard bordered by four wings. The courtyard is private, so the structure is best seen from the street; the sources record no opening times or guided tours.

The building was put up as a coaching inn on the road from Paris to Beauvais, and its round-arched portal opens onto a courtyard lined by four separate buildings. These served as lodgings for travellers, stables for the horses and a coach house for the mail coaches.
