Choir Pool from the Basilique Saint-Urbain de Troyes

The Basilica of Saint-Urbain de Troyes is a massive medieval Church in the city of Troyes, France. It is a classic example of 13th century Gothic Architecture which was heavily resisted by the nearby abbey, who actively tried to damage the building during construction. The church is well known for it's stain-glassed windows dated to around 1295, and the piscine of Saint-Urbain. This is an unusually large recess where the ampoules containing holy oils are placed. Water used in ceremonies is then drained through the piscine in order to be purified.
