2,300-year-old 'secret tunnel' found in Turkey
Archaeologists have discovered a 'secret tunnel' dating back about 2,300 years at the Alaca Höyük archaeological site in Turkey. The site was known as the religious capital of the Hittites, ancient Anatolians who established an empire around 1600 BC. The archaeologists have also found what could be the first Hittite-era skeleton in the world.
