The Casa Fuerte de la Cruceta was finished in 1773 for the purpose of housing cavalry units. The fortress was one of the westernmost defensive positions built in the 18th century by King Charles III of Spain to defend the area of Almería and the Cabo de Gata. It was originally intended to house soldiers who were tasked with guarding the areas between Torre García and Perdigal. The King approved plans for its construction in 1771 and works were completed in 1773. In 1778 the fort had a permanent garrison of 14 soldiers.
By 1830, the fort was abandoned by the army but in 1857, it was transferred to the control of the Carabineros. In 1941, the fort was garrisoned by the Guardia Civil.
The fortress was restored in 2005 and is accessible as a part of the waterfront of El Toyo.
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.
