The first fort is located at the site called Ograde, near the hamlet of Zivaljici in the village of Gardun. It controlled the crossing over the river Cetina from the area of Vojnic and Gardun towards Caporice. The second fort is located above the karstic plateau of Turjacki Podi, on the hilltop known as Radasusa, which controlled the natural route that connected Salona with Aequum. The evidence of these two forts provide a better knowledge of the overall organisation of the garrison in the hinterland of Salona, and by connecting the previous data, it is now evident that this garrison was organised as a complex system of control of the entrance to the main port on the Eastern Adriatic.

The strategic importance of the area of Andetrium is especially highlighted by Tiberius’ inscrip tion from AD 16/17 (CIL III, 3198a + 3200 = 10156a + 10158), which records that the members of legio VII have viam Gabianam ab Salonis Andetrium, aperuit et munit. The outpost at Dugopolje had a similar function16’17. It controlled the entrances from two directions towards Klis, which further led to Salona (Figure 3). The first of the entrances was from the direction of the colony of Aequum, near today’s city of Sinj, which led over Dicmo towards Dugopolje. The second entrance was from the direction of Fig. 1.

The distribution of inscriptions of soldiers in the hin terland of Salona, shows that the legionaries and auxilia ries were scattered across several outposts, which pro vided essential control of natural routes, just like the case of the garrison at Bur num. So far, besides Tilurium and Salona10, the inscriptions of Roman legionaries and aux iliaries were found on very important junctions, such as Klis (legionary: ILJug 2028; auxiliary: CIL III, 8746, IL Jug 2006, 2007), which controlled the only two natural entrances to Dalmatia’s capital; the one from the area of Mucko polje, and the other from the direction of Dugopolje (Figure 2). Both of these areas provided the epigraphical evidence of Roman soldiers as well. In the area of Mucko polje, there was an auxiliary fort, known as Andetrium14’15, which took the name from one of the last strongholds of the Delmatae during the great Illyrican War of AD 6-9 Fig. 3. The location of the military outpost at Kapela in (Cass Dio 56.12.3). Besides auxiliary soldiers (CIL III, Dugopolje (source: Google Earth). The presence of legionaries (CIL III, 2733, 9761,14946, Aequum AE 2008,1058, ILJug 748) and auxiliaries (CIL III, 9760, Mućko ILJug 1963) is also recorded in the wider area of the Clau- Sinjsko polje dian colony of Aequum (todays Citluk near Sinj)19,20. Ac cording to some recent epigraphic discoveries, it is evident Dicmo that the veterans were settled in the area of Aequum even before AD 42 and the Claudian deduction of the veteran Kapela colony21. The main objective of the soldiers dispatched to the area of Aequum was evidently the control of the cross ing over the river Cetina, which was a vital point of the great itinerary road that connected Salona with the valley of the river Sava in Pannonia.

According to ancient itineraries (especially Tabula Peutin- geriana), as well as the terrain configuration, it is clear that there were three major river crossings over the Ceti na. One of them was located near the colony of Aequum, at a place called Mostina (literally meaning »The Bridge«) between Glavice and Obrovac Sinjski22. The other two were located around Tilurium. The first crossing was part of the road that connected Salona with Central Bosnia, and further with Argentaria23. The second crossing was part of another important road that connected Salona with the colony of Narona24, in the valley of the river Neretva. The station at this second crossing was also known as Pons Tiluri (or Ponteluri) in the itineraries (Rav. Cosm. IV 16 = 210.13; It. Ant. 337.5). Fig. 4.
