The word unique is often misused but it rightly describes Le Collateral in Arles: a medieval church that architect Philippe Schiepan has repurposed into a gallery and hotel. All four rooms, all radically different from one another, are meticulously designed and textured. Bathed in ochre, gray, blue and gold, their colors evoke salt, reed, water and sand. Guests often report feeling like they are living in a work of art. Its library and terrace overlooking the city make Le Collateral a perfect retreat for artists or free spirits looking for inspiration.
