Buzovgrad Megalith
If you are up for something unusual to do in Bulgaria, go to the town of Kazanlak, in the heart of the Rose Valley, and climb all the way up to the Sun Gate megalith in the nearby village of Buzovgrad. It is believed to have been the place where the ancient Thracians performed rituals dedicated to the sun. It is also the place where the ashes of one of the most prominent Bulgarian archaeologists and Thracian professionals, Alexander Fol, were spread. Be there at sunrise on the day of the summer solstice to take part in ancient rituals re-enactment.
