Looking through a Château de Tourbillon gate. Sion, Switzerland is a gorgeous place dominated by what look like twin castles on nearby opposing hills. In reality one is Château de Tourbillon, a castle ruin, and the other is Basilique de Valère, a basilica and museum. Either way the effect, the town, and the whole valley is simply beautiful!
