In Orléans, to the east of the Place du Martroi is the massive Cathedral of Ste-Croix, on the site of an earlier 10th C. church, part of the foundations of which have been preserved. The building of the cathedral began in 1278 but was several times interrupted and continued into the 16th C.The west front, flanked by twin towers, has five doorways and much Baroque decoration. The towers themselves are over 81 m/266ft high and are the work of the architect Trouard, although the original plans were drawn up by J. Gabriel.Also of interest is the church treasure, which includes Byzantine fabrics and enamelwork, together with Limoges work.
