The Franciscan Monastery in Humac contains the oldest museum in Bosnia and Herzegovina, founded in 1884. The museum displays Humac Stone Tablet from XII. Century which is the oldest preserved monument written in Croatian (a mixture of Glagolitic and Old Croatian Cyrillic).
Thanks to the collecting activities of numerous Franciscans, as well as various donations from the civilian population, the holdings were continuously increasing, as was the need for new premises for the archaeological collection. Today’s museum exhibition, founded in 2003, is located in the basement of the monastery of St. Anthony of Padua on Humac.
70 Roman monuments were found in the area of the Ljubuški region, of which the largest number are tombstones (stelae) belonging to veterans and soldiers of various legionary and auxiliary units. The museum displays the oldest Cyrillic-Glagolitic monument, which retells the restoration of the church of the Archangel Michael in the period 11/12. century, popularly called “Humac Stone Tablet”. Humac Stone Tablet is the oldest written monument of Croats in BiH.
