Petrina.

Left hand side reads: Petrina under Turkish Rule, Right hand side reads: Petrina under Christian Rule. After the Turkish conquests in the 16th century, western Croatia remained under the rule of the Habsburgs.
In 1592 the Ottomans built a base near the town of Petrinja on the Kupa, the boundary river, and in 1593 Hasan Pasha, its commander, crossed the Kupa but suffered a crushing defeat soon thereafter at the hands of the Croatian Habsburg troops in the Battle of Sisak. The engraving on the left shows the Turkish fort and massive watchtowers in cavalier perspective from the northwest.
A cannon is being fired from the tower in the middle ground. In the foreground is a couple in Turkish dress: the man, whose clothes identify him as a high-ranking Janissary (possibly Hasan Pasha), has planted the shaft of a crescent flag on the ground - a demonstration of the Ottoman claim to the regions on this side of the Kupa.
In 1594 Petrinja was recaptured by the Habsburgs and a new, more modern fortress was erected. The engraving on the right must be seen as complementing the one on the left. It is an isometric plan of the moated castle. The most progressive fortress of its time is presented in the most modern cartographic form then existing.
The river crossing is secured by two pentagonal bastioned ramparts of equal size, ensuring that there is no blind spot for the defenders. Petrinja was henceforth located within that defence belt of the Austrian military border known as Krajina, in which Serbian and Croatian soldier-farmers settled and lived together peacefully up to the early 1990s.
