This early Christian church was modified in the Romanesque era before being destroyed. All that remains today are the open-air ruins (columns of the apse in particular) in a garden. Climb up, carefully, to the top of the campanile (more a ladder than a staircase) and enjoy the superb view of Rab, bay of St Euphemie, string of steeples of the upper town and the tiled roofs of the lower town.
