At the back of Rockhill church there is a wooded area. This area was planted in recent years. Not far back along the path, beside the church, is a Mass rock. This was where Mass was said in Penal times. Fr Daniel McNamara was the parish priest of the area at the time. He was barred from saying Mass in public, so he said Mass at safe houses and Mass rocks. In 1713, he was captured while saying Mass but it is unclear what happened to Fr McNamara after his arrest.
