The town of Kratovo, in Northeastern Macedonia, was a famous mediaeval mining centre. According to travel accounts from the 19th century, the town had eight towers. The remains of four of them were excavated in the first half of the 20th century. The towers served as defensive, fortified residences of the wealthiest local notables. Zlatko’s Tower is considered to be the oldest mediaeval tower in Kratovo. It is a solid structure built of massive blocks of stone on a square area that is approximately six by six metres.
