Salona became a major town under Cesar and under Diocletian, when it had 60,000 inhabitants. The healthy economy and cosmopolitan character of the city encouraged Christianity to flourish here from the 2C. The site now comprises the necropolis of Manastirine, tomb of the victims of Diocletian's persecutions; the museum or Tusculum, an abode built with a large number of recycled Roman elements; the ramparts and the eastern town with an old Episcopal centre and a superb amphitheatre (around 170).
