The Protestant Church in Tullow was previous to the Reformation, Catholic. In the burial-ground round the Church lie the remains of two Catholic priests, Frs. Byrne and Galvin.

There is a subterranean passage leading fro the Church underneath the river to the Abbey burial Ground (Abbeydowne see P. (-) ) where the Augustinian Friars lived. It was used by them as a hiding-place during the Penal Days, both for themselves and for the Sacred Vessels and Vestments.There is nobody living who knows where this underground passage really is.
