The crypt of Saint Girons is a jewel of French Romanesque art. The crypt is all that remains of the church of an old abbey that is now defunct.
The abbey was built in the 4th century , on the banks of the Louts, a tributary of the Adour , on the site of the martyrdom of Saint Girons, evangelizer of the Roman province of Novempopulania. Its creation would date back to the time of Charlemagne , but there is no indication of a religious community until the 12th century when it is recorded in the donations made to the Lescar chapter. The church, damaged during the Hundred Years War and during the wars of religion, was totally destroyed in 1904, saving only the crypt.
The restored vault is supported by columns surmounted by capitals carved with biblical, mythological or vegetal motifs and ornate cymbals . The four central columns are made of red and black marble, originating from an earlier Gallo-Roman building.
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.
