The Kasta Tomb (also known as the Amphipolis Tomb) in Macedonia, Greece, was open to special groups this year. The tomb, discovered in 2012, is significant due to its size and the quality of its artwork. It dates back to the 4th century BC, around the time of Alexander the Great, and there has been much speculation about who might be buried there.

The process of excavation, conservation, and preparation for public display of archaeological sites can take many years, so it's plausible that the site could be open to the public by 2027.

Here are some of the spectacular drone videos that show the monument from above:
