The fishing village of Garrucha suffered at the hands of Berber pirates until the year 1766 when barracks were built at Escobetas, a provisional military building. In 1769, the castle was completed at a cost of 181,000 reais. The fort was designed by the architect Francisco Ruiz Garrido. After its construction, Garrucha began to grow.
It is of masonry construction in three section. The central portion is rectangular with rounded short sides. Attached to the right lateral side, there is a truncated pyramid shape with sloping walls. In its upper part, a parapet is pierced with loopholes. The main body is attached to the left side, of lower height, without openings. It is accessed by an external staircase and one tranche that attaches to the right side.
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.
