One of Ceillac's most distinctive features is the collection of painted sundials decorating the walls of the old stone farmhouses. This is a Queyras speciality — a tradition found throughout the regional park but particularly well preserved here. Some are simple hour-markers; others are elaborate compositions showing hour lines, seasonal curves and inscriptions.
The best examples are on the older buildings along the main lane and on the wall of the church. A slow walk through the village centre reveals half a dozen or more; the tourist office has a leaflet marking the most important ones. They are more interesting than they sound — each one was designed individually, and the craftsmanship is remarkable given the remoteness of the valley.
