In ancient times the centre of Dalmatia was Salona, an ancient town surrounded by the mountains of Kozjak and Mosor through which the river Jadro flows. This is visible in the imposing walls and their towers and gates, a forum with temples, a theatre, an amphitheatre, unique Episcopal monuments and an early Christian church in the cemetery where they buried Salona martyrs (Manastirine, Kapljuč, Marusinac). Most of the findings from Salona are housed in the Archaeological Museum in Split. This important site near Split is the largest complex of ancient monuments in Croatia, and visited by a large number of tourists throughout the year.
