Oryahovo
Oryahovo stands on the hilly southern bank of the Danube, east of the mouth of the Ogosta. A fortress called Kamaka guarded this stretch of river from the ninth to the fourteenth century. In 1396 crusaders on their way to Nicopolis sacked the Ottoman-held town and killed its inhabitants and prisoners. Oryahovo later became an important Danube port, supplying goods to the Ottoman Empire; a book printed in 1762 noted its place in river trade.
