''When one knows the history, one can fight for the good things to be repeated and the bad things not to be repeated'', said caretaker Minister of Culture Nayden Todorov. He opened the exhibition "The Lords of Salt: Provadia - Solnitsata (5600-4350 BC)" at the National Archaeological Institute with Museum at the Bulgarian Academy of Sciences. Minister Todorov pointed out that he envied the archaeologists who were able to hold in their hands artifacts that were also held by other people 7,000 years ago. ‘’This means that we live in a territory where humanity had its development long before in other places in the world’’, Nayden Todorov said.

''Our country hides inexhaustible riches that should be bequeathed to the generations. We should also attract more and more tourists to them'', Vice President Iliana Iotova said at the opening. The temporary exhibition presents over 530 finds discovered during the 20-year study of the salt production and urban center Provadia-Solnitsata.
