This is St Brecan’s Church located in St Columb’s Park and is reputed to be the oldest building in Derry. It was built by Redmond O’Gallagher (the Bishop of Derry) circa 1600. St Brecan was a missionary bishop from the west of Ireland and was possibly the son of a king from Munster. He established a church on the Aran Islands before moving north. He was reputed to have written down prophesies about future wars and the coming of foreigners from England. St Brecan was well traveled and educated in European affairs and is also known as the Bishop of Ardbraccan in Donegal. Strangely too..St Brecan has 2 feast days, celebrated on the 1st of May and also the 6th of December.
