No walls survive, no dedication plaque, no obvious marker. The place retains its identity almost entirely through local memory and the suggestive weight of the townland's own name.

The name Callystown, recorded in various spellings including Kellystown and Calliaghtown, carries within it a possible echo of an older religious presence; the element 'calliagh' relates to an old Irish word for a nun or veiled woman. This is more than mere etymology. According to the historians Gwynn and Hadcock, shortly after 1507 a community of nuns relocated here from Termonfeckin, a coastal settlement a few miles to the south-east. Termonfeckin itself had long ecclesiastical associations, and the move to Calliaghtown appears to have been part of a broader reshaping of religious life in the area during the early sixteenth century. What became of the community after their arrival at Callystown is not clearly documented, and the convent left no standing remains, only a name and a field of stone.
