Patrick's Grave

I took Garald and Carol Lynn to Downpatrick to see the Patrick Center built to educate visitors on the life of Patrick (387 - 460 AD)  We parked above the center at the Down Cathedral and wandered into the graveyard where there was a small wooden sign that said 'St Patrick's Grave.' 
Remembering that Randy Lee ran up on a rainy day, I wondered if he got to see this.  The rock has a very old inscription of a cross and the word 'Patri' with the rest worn away.  The plaque says the remains of St Patrick, St Brigid and St Columba, are reputed to be re-interred here in the 12th Century.
