The old town and medieval castle of Kršan lies on the hill, while new town and village is along the road. The castle is first mentioned in 1274. It was abandoned until the 13th or early 14th century, when it was rebuilt byHeinrich III. Until 1374, when counts of Gorizia became extinct, it was in duality of governance, between the real masters Counts of Gorizia, and Aquileia church in which name the Counts ruled over the castle. When the counts extinct it wasn't returned to Aquleia patriarchs (the state Patria del Friuli), but was inherited by Habsburg family.
The Habsburg family gave it to their vassal Krotendorfer or Cherstlein family. Since then the castle is mentioned as Kršan (Kerschan). They kept it until 1631, with short interruptions when its lords were families Devinski (1388–99), Walsee (1399-1431) and Wolf (1431–36). Later as lords are mentioned de Fini, Auersperg, Rampelli, Benvenuti dell Argenti, Josip de Sussani (who found the Istrian Demarcation from 13th-14th century), then his nephew Franjo Scribani, then nobleman from Plomin Matija Tonetti, and as last Giovanni Tonetti.
From the medieval castle is well preserved the tower of quadrangular layout, while residential and defensive complex was renovated in new residential buildings. The town is entered on the east side of the completely preserved city gate, on the right hand the city defense wall leans a number of houses of which the first is the old municipal house. In the inner courtyard of the castle has been preserved foursquare frame of Gothic portal from the 15th century, and well throat with engraved year 1666. The two-nave parish church of St. Antun was built in the 17th century, and the most of the church furniture dates from the 18th century. At the cemetery is nave chapel of St. Jakov from the 15th century. On the floor of the church, paved with brick and stone, are gravestones of feudal lords from the 15th, 16th and 17th century, particularly the plate from 1415 of Juraj Kršanski in a Latin epitaph inscribed with Gothic letters.
