Misionis is an ancient Bulgarian city from the era of early Byzantine culture (5th - 7th centuries) and medieval Bulgarian culture (9th - 14th centuries). It is mentioned three times in the book "Entertainment of the Longing to Travel the Countries" by Muhammad al-Idrisi. It is believed that the mentioned Misionis coincides with a medieval Bulgarian city located 7 kilometers from the city of Targovishte, in the Preslav Mountains. It is part of the Hundred National Tourist Sites. In the 1960s, the ruins of a fortress were discovered, located on an area of ​​19 decares, which local legend associates with the victory of Khan Krum over the Byzantine emperor Nikephoros. Fortress walls with towers, two basilicas (5th - 7th centuries), an early Bulgarian settlement (9th - 10th centuries), a gate of the late medieval fortress (12th - 14th centuries) mark the beginning. Misionis was a large and flourishing, commercial and spiritual Christian center, which existed from the beginning of the 4th to the end of the 14th century. A description is given to us in the 12th century by the Arab traveler Al-Idrisi. He tells of “…a large, populous city, founded in ancient times... There is an office for Russia in it. It is a flourishing city. It has populous markets and abundant natural resources. It is located on a mountain.” The fortifications surround an area of ​​120 decares, and at its peak in the 14th century the city spread over 700 decares. For ten centuries, Misionis played a key role in the trade of early Byzantium and the Bulgarian medieval state, with importance for the defense of the Bulgarian capitals Veliki Preslav and Veliko Tarnovo. The flourishing city was mercilessly plundered, destroyed and burned by the Ottoman conquerors at the end of the 14th century. Today, the findings from the explorations of the town of Misionis are displayed in the permanent Archaeological exhibition of the Regional History Museum - Targovishte.
