Pazin Castle: the great cliff-edge fortress of inland Istria

Pazin Castle (Kaštel Pazin) is a medieval fortress built on a solid rock in the middle of Pazin, the administrative seat of Istria County. It is the largest and best-preserved castle in Croatia's westernmost county and overlooks a deep gorge where the karst river Pazinčica sinks underground. Today it houses two museums, which makes it an easy and rewarding stop in inland Istria.

Pazin Castle stands on the very edge of a cliff, and below it a river simply disappears into the ground. In more than a thousand years its walls were taken by force only once, in 1508.

The history of Pazin Castle

The castle first appears in writing as Castrum Pisinum, in a document issued on 7 June 983 by the Holy Roman Emperor Otto II, which confirmed its possession to the bishop of Poreč and an earlier grant of 931. In the 12th century the bishops handed it on to Meinhard of Schwarzenburg, and it then passed to Meinhard I, Count of Gorizia, and to Meinhard, Margrave of Istria, and his successors. The historian Camillo de Franceschi described the earliest building as a simple, strong structure: an elongated rectangle with a ground floor and two upper storeys, a square tower, and walls that also enclosed the castle chapel.

When Albert IV of Gorizia died without heirs in 1374, the castle fell to the House of Habsburg. Over the following centuries the Habsburgs leased or mortgaged it to noble families such as Auersperg, Walsee, Eggenberg, Khevenhüller and Fugger. For all that time it was the administrative seat of the County of Pazin, also called the County of Istria, which bordered Venetian lands in western and southern Istria and faced constant pressure from Venice. A sizeable garrison therefore lived behind the walls, and the complex was run by noble captains or castellans, because the owners rarely lived in Pazin themselves.

The walls are between 80 and 380 centimetres thick. Although the castle was attacked many times, it was taken only once, in 1508, when Venetian cannon fire badly damaged it; the Habsburgs won it back by military action the next year. As the threat of war faded, the tall towers, above all the dominant square keep, were lowered in the 18th century to the level of the other walls and roofs, some loopholes were walled up and windows were opened.

In 1766 the castle was bought by Antonio Laderchi de Montecuccoli, whose name it carries in Italian. After the Venetian Republic fell in 1797, Pazin belonged to the Habsburg monarchy, then briefly to Napoleon's French Empire, then again to the Habsburgs, to Italy in 1918, to Yugoslavia in 1945 and to Croatia since 1991. Today the Pazin Town Museum and the Ethnographic Museum of Istria are housed inside.
