Beglik Tash is a prehistoric rock sanctuary situated a few kilometers north of the city of Primorsko. It was re-used by the Thracian tribes in the Iron Age.
Most of the megaliths have traces of carvings for the purposes of Thracian rituals. There are also the remains of a labyrinth that visitors can pass through. A Thracian sun-clock is formed from huge stones. There is also a 150-ton rock that rests on the ground in only two places, and a 'womb-cave'.
Archaeologists have found ceramic artefacts from the Early Iron Age (10th–6th century BC), classical antiquity, and the Middle Ages, as well as a man-made stone altar at the end of the natural cave which proves that it was used as a place of worship. Every day at noon, a ray of sunlight enters the narrow entrance of the cave, and projects itself on the back of cave. According to the Bulgarian archaeologist Alexander Fol some of the Thracian womb-caves had the property of letting the sunlight in only at certain times of the day, a natural phenomenon seen by the Thracians as acts of symbolic fertilization of the Earth womb or the Mother Goddess by the sun phallus of the Sun God.
The site is an open-air museum maintained by the Burgas Historical Society. Beglik Tash is located in the vicinity of two other Thracian sites: the city of Ranuli and the fortress of Pharmakida in the Strandzha Mountains.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
