Option 1 - The Salt Mine/operates in AUG and SEP Continue to the nearby Salt Mine "Solnitsata", the oldest salt-production and urban center in Europe (5600–4350 BC). The prehistoric complex Provadia-Solnitsata is located near the modern town of Provadia in Northeastern Bulgaria. It represents the remains of the oldest known salt production center in Europe, which later developed into the first prehistoric urban center on the continent (4700–4350 BC). The complex consists of a salt-production area with ritual pits, an unfortified and later fortified settlement with massive stone walls, a ritual zone, and several necropolises. The emergence and development of the site are directly linked to the largest and only rock salt deposit in the Eastern Balkans, the so-called Mirovo salt deposit, on which the complex is situated. "Solnitsata" presents you a great opportunity to get archeological insights into prehistoric life. After a delightful trip, return to Varna in the early afternoon.
