The ancient archeological site of Gračine is located on the flat plateau above the left bank of Trebižat River in the area of the village Humac. The military camp originates from 1st-3rd century, and was partially researched and restored in the period from 1977 to 1988. Remains of a Roman military complex have been excavated at the site. Numerous remains of pottery, jugs, vases, coins, jewelry, rings, glass, tools and weapons were found during the excavation. A small part of the exhibits is in the Museum of the Franciscan Monastery of St. Ante, and most of the excavations (ceramics, glass, numismatics) have never been exposed. This archeological site was declared a national monument in 2003.
