"Gradina" in Cista Velika, on the height of around hundred meters, in the north-western direction from the St Jacob church, is a prehistoric fortification that originates from the Iron Age. Walls of the fortress are preserved on the eastern, northern, and western side, while on the southern side it was protected by a steep cliff. The fortification is of minor dimensions and the area between the walls occupies a very little surface, therefore, there is a possibility that there was also a little settlement along its southern side. The fortification in Cista Velika is one of the most important fortifications in this area of continental Dalmatia, and it directly controls the ancient path that is still being used, leading from the valley of Cetina towards the east. The ancient settlement (Tronum) was situated on the area where today is the new part of the cemetery, as well as on the positions of Aptovac and Crkvine, more towards the south.
St Jacob church, as it is today, was built in 1888 on the same location where earlier used to be a church from the 18th century. Even that church was probably constructed on the same location where there used to be a more ancient church, i.e. a medieval church, along which was created a cemetery with stećaks. There is almost nothing left of the church from the 18th century, except the relief built in the southern surrounding wall – monogram of Christ and Wounded Heart of Jesus – a symbol of the local craftsman from Omiš who used to work on the church in 1755. There are two valuable wooden altars from the family Rako workshop, among which the main altar might be the biggest that has ever been created in that workshop of the town of Imotski at the end of the 19th century.
