Lombez Cathedral is a brick church with an ornate pink-and-white five-tiered octagonal bell tower constructed c. 1346. A plaque to the right of the plain west entrance records the visit of the Italian poet Petrarch in 1330, arranged by the bishop, Jacques Colonna (1328–41), also of Italian extraction, who made Petrarch an honorary canon in 1335. The typical blank west façade of meridional Gothic is relieved only by a small roundel and the Flamboyantentrance in stone. The severe exterior is characteristic of the region with tall buttresses around the chevet.
Below the tower in the interior is a remarkable 12th-century baptistry, which was part of an earlier church. The lead baptismal font is made of two pieces, the lower part decorated with religious figures in medallions in the style of the 13th century, and the upper part with a frieze of secular scenes of antique design. The stopper in the base suggests it was used for total immersion which was practised until the 9th century.
Other items of note are the 17th-century walnut choir stalls, the altar in Carrara marble consecrated in 1753, and the 18th-century organ at the west end. The three panels of brilliantly colored 15th–16th-century glass in the chevet are by the followers of Arnaud de Moles, restored in the 19th century, and illustrate scenes from the Life of Christ and from the Passion. The rest of the glass is 19th-century.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
