The abbey of Conques and its dominant church dedicated to St Foy is today one of the most prominent examples of the harmonic interrelationship between medieval sacred architecture and nature. Surrounded by hills that drastically change colors during the year, the abbey is situated on the south-facing slope tens of meters above the confluence of rivers Dourdou and Ouche that flow along the valley. This paper analyzes the ways in which the landscape on one hand and the abbey church of Conques on the other were activated within paraliturgical and liturgical celebrations. It is divided into three sections moving on the axis from the landscape of Conques and the way people thought about it in the Middle Ages, to the process of sacralization of that landscape, and to the discussion about the vigils of St Foy and the role of liturgy in experiencing St Foy’s reliquary in and especially around the church.
