Tarbes Cathedral was established during the 12th century. There remain two apses of the choir. A first extension was made in the 14th century by the addition of a Gothic nave. Its extension extended until the 18th century with the outer span. The cathedral resembles a fortress as it was built with round pebbles from the river Adour which have also been used for the construction of many houses in Tarbes. It can accommodate up to 600 people.
A large baroque canopy in marble from the 18th century houses as the main altar.
The cathedral also includes a chapel of the Blessed Virgin in which visitors can read the testament of Louis XVI engraved on a black marble wall three meters high. Another peculiarity is that there is a treasure house and within there are ornaments, chasubles and old bishops' sticks.
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.
