Cantina e Cucina restaurant in Rome, via del Governo Vecchio, very close to Navona place. Very good food, staff talking at least English, German, French...and Italian ! I recommend the Tiramisu de la casa, unique.
Knights templar vault in Aragnouet, Hautes Pyrénées, France. Chapelle Notre Dame de l'Assomption du Plan (ou chapelle des Hospitaliers de Saint-Jean de Jérusalem). It was build during XI and XII centuries.
