The city of Lauro is known for the imposing Lancellotti Castle, built in the 11th century in a beautiful panoramic position. The first written mention of the Castle appeared in a document of the 10th century, the owner of the 'Castel Lauri' was a certain Raimundo.
The castle was set on fire by the French army in 1799. The building, which appears today as it was reconstructed in 1872 by Prince Filippo Lancellotti, was inaugurated on the same year on the feast day of the patron saints, August 25th, and presents a composite architectural style of Gothic, Renaissance, Neoclassical, and Baroque. T
he castle stands in a small and elegant 19th-century garden, with a central circular fountain that was previously part of a large 17th-century park destroyed during the events of 1799. To the right of the Renaissance wooden portal is the stable, which houses a remarkable 17th-century statue. At the back, a small gate leads to the secret garden, while the family chapel and part of the private apartments are located behind. In front of the avenue, a short bridge connects the courtyard to the residence.
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.
