Bertalan Vilmosné: Az óbudai klarissza kolostor

Details of the 14th century cast floor of the mediaeval house (Father István's house) cut into two by the fence, with the remains of a 12th or 13th century horseshoe shaped stove. The mediaeval fence was built right on top of the pillar of a 4th century aqueduct. Around the pillar of the Roman aqueduct having two pipes embedded in stone there were remains of a mediaeval house (a well-house?). In the foundation of the fence at the wall of the aqueduct there was walling-in. There were further Roman remains underneath the 4th century aqueduct. Viewed from south-west. Details presumably belonging to the well-house.
