The name of the town originates from the Roman military camp Quadruvium, meaning crossroads, which once stood around the Valigaštar spring. Today, Karojba, the seat of the eponymous municipality established in 1997, is known for its botanical landmarks - three pine trees adorning the road to Pazin. The uniqueness of these umbrella-shaped pines lies in their ability to thrive deep inland, far from the coast.
In the territory of the Karojba municipality, the Mirna River basin includes watercourses such as Krvar, Kamnica, and Špina, along with two smaller streams, Žunji and Milići, flowing into Krvar. The Krvar stream, a left tributary of the Mirna River, serves as a natural boundary between Karojba and the Municipality of Motovun on the western side. According to legend and historical records, the name of the stream derives from the blood of wounded and fallen soldiers during a battle of the early Middle Ages, marking a fierce struggle between invaders led by Attila and indigenous inhabitants defending their land.
Karojba boasts a rich cultural heritage, including several significant churches. The Church of Saint Magdalene, built in the 12th century in the Konobari hamlet, stands out with its roughly built stone altar and a bell dating back to 1607. The Church of Saint Nicholas, located in the Rakotule cemetery, dates back to the 14th century and is known for its Glagolitic graffiti and fresco segments. The Church of Saint Roch, built in 1580, and the Church of Our Lady, built in 1617 on the Šublenta hill, have undergone alterations and renovations, with the latter containing a stone altar with a wooden statue of the Blessed Virgin Mary.
Karojba leaves an impression of a unique atmosphere, combining rich history with rural charm and diverse terrain, from hilly slopes to fertile valleys, creating a distinctive ambiance that is hard to find elsewhere.
