Pazin (Pisino, Mitterburg) is a town in western Croatia, the administrative seat of Istria County. It is known for the medieval Pazin Castle, the former residence of the Istrian margraves.
The town had a population of 8,638 in 2011, of which 4,386 lived in the urban settlement. In 1991 it was made the capital of the county for its location in the geographical centre of the Istrian peninsula and in order to boost the development of its interior territories.
Pazin was built in an area rich in history and inhabited since ancient times. The burg surrounding the castle was inhabited since prehistory. Some of the surrounding rural settlements, such as Glavizza, Vermo, which features a necropolis dating from the 7th to 5th century BC, and the castellieri of Bertossi, likewise inhabited since prehistoric times, developed into urban centers, while others became burgs around newly built castles, and others still remained rural villages. Just to its southeast lie Gallignana (Gračišče), castrum Callinianum in Roman times, and Pedena (Pićan), which was settled by the Histri, and then became a strategically important Roman military settlement under the name Petina. Some historians also link it to Pucinium, an unidentified fortification in central Istria, whose wine was famous even at the Roman court, with Livia, wife of Emperor Augustus, believing that her longevity was due to it. Just to the north of Pazin lies Draguccio (Draguć), formerly part of the County of Pazin as well as the Pazin county, which was a Roman fortification, and where numerous Roman archaeological finds were uncovered. The areas of Pazin, Draguć (Draguccio), Buzet (Pinguente) and Roč (Rozzo, an important Roman castrum since the 2nd century BC) are rich in Roman finds.
The current settlement of Pazin originated with the houses built around a castle erected by Germanic rulers. These were the houses of the family relatives and feudal settlers, to which were later added those of the foreign artisans, who offered their services to the lords of the castle as well as their employees and subjects.
