Theobald I ordered the construction of the Tiebas castle around 1250 and since then it has suffered throughout history.
It survived numerous attacks quite well until an attack by Castile in 1378 ended with it on fire. With it, burned a good part of the Navarre Archive, and this has deprived us of a lot of information about our history.
Luckily, in 1512, it managed not be demolished under Cardinal Cisneros. Then it witnessed a bloody battle in 1810 between four battalions under Espoz y Mina against more than 3,000 French soldiers.
In the end, after being abandoned, many of the stones were taken from the castle, and work is being done now to consolidate the structure.
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.
