Santa María de Toloño is a ruined Spanish monastery located in the Sierra de Toloño near Labastida. Constructed by the Hieronymites, the monastery was destroyed in the First Carlist War and only a few walls remain.
The sanctuary is located in a meadow at 1,201 metres above sea level. It was built by the Hieronymites between the 14th and 15th centuries, and abandoned in 1422 due to harsh weather. Later, it was affiliated with the Hermandad de la Divisa (Brotherhood of the Currency) until the end of 18th century. In 1835, during the First Carlist war, it suffered a fire that left only a part of the Baroque chapel standing.
The building was well-constructed, with church, camarín and sacristía. Its retablo mayor were of white stone. There were 22 rooms, five kitchens, separate rooms for a chaplain, two hermits and a servant, as well as a meeting room for the Divisa.
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.
