Mirje is a late antique site on a hill above Postira. The remains of the medieval Benedictine monastery of St. Stephen, which is mentioned in the Povaljska listina, are located on the site.
There was a Roman villa on Mirje in ancient times, and an early Christian basilica was built on its foundations in the 6th century, from which a monastery grew.
Today, although only the remains are visible, the site provides an impressive picture of Brač past with a beautiful natural environment from which you are only half an hour's walk from the centre of Postira.
