In the area of Trilj there are many archaeological findings dating way back to Mesolithic. The first ethnic group that inhabited this area are the Illyrian tribe Delmati. Delmati people lived in a hill forts along the communication lines that connected their capital Delminium with the Adriatic coast. Hundred and fifty years of fierce fighting against the Romans (165 BC.- 9. AD) ended in defeat of Delmati people, after which Romans built the legionary fortress Tilurium on the hill above Trilj.^[4]

At the top of the hill of Gardun, just 1 km south of Trilj, remains of a legionary fortress at Tilurium can be found. Tilurium guarded the entrance to the Cetina valley from the south and the approach to the provincial capital at Salona.^[5]

It is situated 8 kilometres (5.0 mi) from the town at an altitude of 705 metres (2,313 ft) in a strategic location enabling its crew to oversee traffic of goods through the mountain passage that goes through the Dinaric Alps and leads to Bosnia. The first written record of this fortification dates to 1345.^[6] First written record of fortification dates to 1345.^{[citation needed]}

Nutjak fortification is situated at the entrance of the Cetina river canyon, on a cliff. Fortress was built in the 15th century by nobleman Žarko Dražojević to protect land west of Cetina river from Ottoman invasion. ^{[citation needed]}
