On the Open Doors Day, organized once again on September 22, Provadia-Solnitsata was visited by around 1,800 enthusiasts of antiquity. To facilitate the tour of the archaeological site along the designated route, our guests entered the site in groups of 50-60 people. All of them were personally welcomed by the head of the archaeological excavations, Acad. Vasil Nikolov, at the entrance of the complex. With a brief speech, he introduced them to the results of the research conducted so far and explained the importance of salt in antiquity.
