Apart from the beaches, Petrovac’s most interesting attraction is also its least heralded. In 1902 the foundations of a Roman building complete with mosaics, probably dating from the 4th century, were discovered in an olive grove and here they remain in a precarious state of preservation. A glass shed covers a section of mosaic roughly 10m by 15m; it’s invariably locked but you can peer through the windows. Around the shed, extensive brick foundations can be seen.
The site is a little tricky to find: take the path leading through private land opposite St Thomas’ Church (Crkva Sv Tome) – which is itself around 500 years old and was, at the time of research, being restored. Make your way through the olive grove to the dig site where you will need to watch your footing.
