Trnava, Gornji Bogićevci
About this place
Trnava is a small village in the municipality of Gornji Bogićevci, in the western part of Brod-Posavina County. It is one of the municipality’s six settlements, yet its historical importance lies in the Bedem–Varošine site, also known as the Fort of St John of Trnava. Archaeological and conservation research identifies it as a 13th- and 14th-century crusader fortification associated with the Templars and Hospitallers. Travellers should therefore not expect a standing tower or a reconstructed castle; the appeal is a medieval site whose story survives in the terrain and excavated remains. County documents show that work has continued in recent years: funding has been assigned to archaeological and conservation research at the Hospitaller fort, while the municipality’s listed projects for 2023 included work on the Trnava rampart. Trnava is consequently best suited to visitors interested in the quieter layers of western Slavonia’s crusader and military history, beyond conventional museum displays.
Trnava’s identity comes not from a compact centre but from the village’s relationship with the medieval St John of Trnava site at Bedem–Varošine. Archaeologists have investigated remains of 13th- and 14th-century defensive architecture linked to Templar and Hospitaller estates in western Slavonia. Administratively, Trnava belongs to Gornji Bogićevci municipality alongside Dubovac, Kosovac, Ratkovac, Smrtić and Gornji Bogićevci itself. The limited visibility of the ruins shapes the experience: this is an archaeological landscape rather than an intact fortress. Recent county support for research and work on the rampart further underlines that the crusader-era site is the village’s defining piece of cultural heritage.

Things to do
The most rewarding way to explore Trnava is to read the landscape around the medieval St Ivan Trnava site rather than expect a formal museum complex. The archaeological account records an oval fort core, a central circular hollow eight to nine metres wide and a south-eastern edge cut measuring roughly 35 by 12 metres. Its historical context is unusually vivid: Ivan Morovićki took castrum Tornow by force in 1403 and was struck by an arrow during the siege. A visit can continue through the municipality’s foothill countryside towards Gornji Bogićevci, where municipal services and the principal local road connections are found.
