The Euphrasian Basilica complex, including a sacristy, baptistery and the bell tower of the nearby archbishop's palace, is an excellent example of early Byzantine architecture in the Mediterranean region. The Basilica has been inscribed on the UNESCO World Heritage List since 1997.
The earliest basilica was dedicated to Saint Maurus of Parentium and dates back to the second half of the 4th century. The floor mosaic from its oratory, originally part of a large Roman house, is still preserved in the church garden. This oratorium was already expanded in the same century into a church composed of a nave and one aisle (basilicae geminae). The fish on the floor mosaic dates from this period. Coins with the portrayal of emperor Valens (365–378), found in the same spot, confirm these dates.
The present basilica, dedicated to Mary, was built in the sixth century during the period of Bishop Euphrasius. It was built from 553 on the site of the older basilica that had become dilapidated. For the construction, parts of the former church were used and the marble blocks were imported from the coast of the Sea of Marmara. The wall mosaics were executed by Byzantian masters and the floor mosaics by local experts. The construction took about ten years. Euphrasius, holding the church in his arms, is represented on one of the mosaics on the apse, next to St. Maurus.
Following the earthquake of 1440 the southern wall of the central nave of the basilica was restored, so that in place of the windows which were destroyed, other were built in the Gothic style.
The most striking feature of the basilica are its mosaics, dating from the 6th century. The mosaics which decorate the inside and facade of the church are considered a valuable bequest of Byzantine art, and thanks to the floor mosaics and preserved writings the periods of its construction and renovation can be read.
The apsis is dominated by the marble ciborium, modelled after the one in St. Mark's in Venice, it was built in 1277 on the orders of Otto, Bishop of Poreč. The canopy, decorated with mosaics, is carried by four marble columns that belonged to the previous 6th-century ciborium. The front side of the canopy depicts representations of scenes from Mary's life, the Annunciation. In the 15th century Bishop Johann Porečanin ordered in Italy a Renaissance relief for the antependium of the altar, made of gilded silver. The polyptych of the Venetian painter Antonio Vivarini dates from the same period. The Last Supper, painted by Palma the Younger is a Baroquework.References:
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
