Château d'Urtubie still belongs to the same family since its construction in 1341. Additions and improvements were carried out in the 16th and 18th centuries and the castle is today a historic monument, furnished and decorated with refinement .
The stones of Urtubie tell six centuries of history of the Basque Country . King Louis XI sejourned in the castle in 1463 and Louis XIV raised the domain to the status of viscounty in 1654. In the 19th century Soult then Wellington were known to the castle during the Napoléonic wars.
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.
