Visit Kojsko, a scattered village with 300 inhabitants overlooked by a hill (elevation 290 m) with a Church of Saint Cross on the top. According to oral tradition, the church used to be called Saint Cross on the Lake, which is hardly surprising since numerous springs really come out from beneath the hill. The church was built around 1500 and is part of a former fortified village; the last of its fortified crenellated towers is today a bell tower. The path leading to the church is lined with Stations of the Cross chapels, while its murals originate from the second half of 17th century. Once a popular pilgrimage destination visited by pilgrims from Carinthia, Friuli, Gorizia, as well as from Vipava and Posočje regions, the Church of Saint Cross remains today primarily an interesting tourist attraction. The main Gothic wing altar was made in the Villach carving workshop in 1515 and is one of the oldest Gothic altars in Slovenia. The place is exceptionally panoramic, offering views all the way to the Alps and the Adriatic Sea in fine weather. It is said that from here, the Italian king observed battle positions on Sabotin during the Battles of the Isonzo. The preserved 300-meter single-track railway tunnel named “Na kalehih” indicates the strategic importance of the village during World War I. The Church of the Assumption is also interesting – it was rebuilt in the Baroque style in the second half of 18th century with the presbytery preserved from the Late Gothic period.

Unfortunately, only a few remains (a tombstone with inscription plates and coats of arms of the Coronini and Dietrichstein families) of the once most beautiful castle in Brda can now be seen. In 18th century, the castle was the focal point of cultural activities in the Gorizia area and, as it was also the seat of judiciary, justice was delivered here for almost entire Brda region. Before World War I, Kojsko was the economic and cultural center of the Brda region. Today, however, it is a distinctly wine-growing oriented village. A post office, a health care center and a restaurant are located there. Beside the road, you can see a monument dedicated to Srečko Kumar, a famous choirmaster and musical pedagogue.

In 1086, Kojsko is mentioned for the first time as a village given to Rosazzo Abbey by count Henrik of
Gorizia. In 1879, the first wine tasting, exhibition and wine competition was organized in the village. Every year they also celebrate St. Cross holiday and stage a procession.
