A home with history. At 138 years old, Brun Arche carries the character of its past. Expect charm, idiosyncrasies, and a sense of place that modern builds simply cannot replicate.
Brun Arche is more than a place to stay—it’s an immersion into an unhurried way of life, where days unfold to the rhythm of the river and evenings are measured in golden light and quiet conversation. It is, at its heart, a home—not just for those who stay, but for those who embrace its story.

• The Parlour – A cozy retreat with deep armchairs and a discreet Roku TV for the rare rainy afternoon.
• The Dining Room – Seats 6-8
• The Bar – A former butler’s pantry turned wet bar, the perfect prelude to an evening on the breezeway.
