escaped almost unscathed. Building description Over the entrance is a modern window showing the figures of the cathedral founders of 1048 and 1218 (bishops Geoffroy de Montbray and Hugues de Morville); in the centre is the figure of Saint Ereptiole, believed to have built the first church in Coutances. In the south aisle is a pillar with a carved capital depicting medieval ladies. The lantern tower is designed to provide an intense source of light in the centre of the cathedral. Eyes are drawn to the circle at the centre which is meant to represent Heaven, while the earth is the square, and the octagon represents the Resurrection. Behind the principal altar stand six pairs of pillars supporting the roof, which are said to stand for the Twelve Apostles. The windows date from the 15th century. The south ambulatory contains the Chapel of Saint Joseph, with a wall painting of 1381 that depicts the Holy Trinity of God the Father, Christ on the Cross, and the Holy Spirit as a dove. The Chapel of Saint Laud, also in the south ambulatory, is one of the oldest parts of the cathedral, dating from the 13th century. The stained glass window shows details from the life of Saint Lo, including the saint celebrating mass with the dove of the Holy Spirit appearing above the altar. (His helper holds the hem of his robe to prevent him stepping back on to it and tripping.) The north ambulatory contains the Chapel of Saint Marcouf, with a window showing scenes from the saint's life. The north ambulatory also holds the holy oils (chrism) used during the sacraments of baptism and extreme unction, confirmation, and at the ordination of priests. The north transept displays a 13th-century stained-glass window showing scenes from the lives of the saints Thomas Becket, George and Blaise. The floor of the north aisle is laid with medieval tiles decorated with the fleur-de-lys, or lily, the emblem of the French royal family (and a symbol associated with the Virgin Mary). Other tiles show the arms of Castile, next to the fleur-de-lys of France. The baptismal font is located in the north aisle. The cathedral has had an organ since before 1468. The current organ was built in 1728 and has four keyboards or manuals, 51 stops and a pedal board. The west window is partially hidden by the organ. Above the south porch
