It was here in 15th March 1594 that two men came looking for treasure and supposedly came across a cave where they found some lead plates. Written in Arabic, these told the story of the martyrdom of St. Tesiphon. The Archbishop ordered further excavations, and some remains, more plaques describing the martyrdom of St. Cecilio, St. Tesiphon and St. Hiscius, and also an oven and some ashes were found.
