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 Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
