Kaliakra is a long and narrow headland in the Southern Dobruja region of the northern Bulgarian Black Sea Coast, located 12 km east of Kavarna and 60 km northeast of Varna. The coast is steep with vertical cliffs reaching 70 m down to the sea.
In 4th century BC a settlement called Tirrisis was founded bearing the name of a local Thracian tribe. In Roman times the fortress rapidly grew – lots of public buildings and facilities were built. There were plumbing system, churches, public baths (Roman thermes), fortification walls most of which can still be seen today. The cape became a strong Bulgarian fortress and flourished in the second half of the 14th century as a capital of the Dobrotitsa dukedom. It was a powerful medieval town minting its own coins. The fortress declined when it was conquered by The Ottoman Empire.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
