I visited the site in 2009. The region has been populated since the end of the 7th millenium when the hunters - gatherers settled down. A fire burnt the wooden walls of the two dwelling but "baked"(preserved perfectly) the clay foundations. I saw the walls, an oven, stone grinders, a clay bed, ritual stones ... The duplex is enclosed in a special museum which exhibits lovely ceramic from the neolithic and chalcolithic eras in the adjacent rooms.The experience is amazing, showing how sophisticated people were 8 000 years ago! The site and the whole region is long overdue to be included into the WHS list!

Also the new Regional museum of History in Stara Zagora is an architectural marvel, built above an ancient Roman street!The city is 2.5 hours drive from Sofia.
