The Tito Bustillo Cave is a prehistoric rock shelter located in the small town of Ribadesella. The cave was inhabited by humans (cro-magnon) before the year 10,000 BC. Due to the collapse of the rock, the original entrance to the cave was sealed thousands of years ago, which made it possible for preservation of objects, tools and wall paintings that were discovered in 1968. Based on those objects found in the cave, it is known that there was a significant human presence during the Magdalenian culture of the Upper Palaeolithic, but the cave was probably inhabited before that time.
The Tito Bustillo Cave has been designated a World Heritage Site, as part of the Cave of Altamira and Paleolithic Cave Art of Northern Spain, and it counts with 12 prehistorical paintings, making it one of the most complete examples of the prehistoric art in the north of Spain. The oldest of these paintings shows human figures and is around 33,000 years old, as determined by radiocarbon dating. Some scientists believe it could have been made by Neanderthals, though this theory hasn't been proven.
Some of the paintings represent animals: horses, deer, moose and even a marine animal (probably a whale) and they are believed to have had some kind of ritual purpose to improve their hunting. There is also a panel representing female genitalia and it is believed to have had the intention to invoke fertility. The oldest painting in the cave represents an anthropomorphic figure, part male, part female.
Apart from the paintings, some objects from the Magdalenian period were perfectly preserved. The most important ones are some harpoons made of bone and a carved staghorn of a goat head.
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.
