The Zidine archaeological site is located in Gornja Skakava, approximately 20 km from Brčko.

At the highest point of the hilly elevation where the site is situated, the Chapel of St Francis was built in 1983.

The archaeological site consists of the remains of the foundations of a Gothic monastic church, a Romanesque church, an older sacred complex (baptistery), a necropolis and a range of archaeological finds. Remains of structures dating from the pre-Romanesque period to the late Middle Ages have been discovered at the site, too. A large number of stećak tombstones, as well as graves located inside and around the church, have also been found.

The baptistery is the oldest archaeological find. It had a hexagonal ground plan. Baptisteries of this type are associated with early Christian church buildings and have existed since the pre-Romanesque period in Dalmatia. The Romanesque church dates back to the 13th century. The remains of the walls of a single-nave church, measuring 13.22 × 7.66 metres, have been discovered, whose perimeter walls were almost entirely removed, as their material was used for the construction of the monastic church. The church had an eccentric ground plan with a vaulted semicircular sanctuary, above which there was a flat ceiling.

The Gothic monastic church dates from the first half of the 14th century. The ground-level zone of the walls has been uncovered. The single-nave church measured 23.50 × 9.16 metres, with an elongated polygonal sanctuary framed by buttresses, which was vaulted in accordance with Gothic architectural principles. On the northern side of the sanctuary, there was a sacristy, which was later added to the church structure. Nine stećak tombstones were found inside the nave of the church, as well as seven outside the church. Three of them were decorated.

Five graves were found inside the church, and four outside. The graves were skeletal burials, all covered with stone slabs or chests, which was a rare feature in medieval churches in Bosnia and Herzegovina.

In addition, a medieval cemetery was discovered, with graves arranged in rows. Recent research has revealed accompanying grave goods, such as a silver ring, a fragmented iron clasp, three silver coins and five decorated plaques.

The archaeological finds from the graves are kept in the parish church of the Franciscan Monastery of St Anthony of Padua in Dubrave.
