In the realm of unlikely trends: ancient monasteries are being reinvented as luxury hotels with rigorously chic interiors. Among the most stylish—and least remote—is Kruisherenhotel, carved out of a 15th-century church complex near Maastricht’s main shopping district. Hotelier Camille Oostwegel, known for smartly repurposing crumbling Low Country châteaux as luxury accommodations, assembled the new 60-room hotel inside the church’s exoskeleton. A cardinal-red runner suspended in the nave and choir leads to a dining loft that resembles an erector-set project. Ingo Maurer’s quirky “flying saucer” chandeliers hover from the vaulted ceilings, and the chancel houses a wine bar with tufted-velvet banquettes. In the bedrooms, massive support beams emerge at curious angles from the wall.
