In a landscape of forests and orchards at the heart of the Oltet gorge, this unmissable spot derives its name from a medicinal plant used by the Dacians. Beyond the carved wood doorway, the white church in the centre of the courtyard is a commission of Constantin Brâncoveanu, as are the wall paintings (workshop of Constantinos) including portraits of the founders among others. Head on the grotto, one of Europe’s largest. This huge cave in the limestone rock has been known since Dacian times.
