I know I've said it before, but if you ever find yourself walking around the Walls of Derry-Londonderry a must is a visit to St Augustine's church. We were there a couple of weeks ago, with The Brother and his daughter. Compared to St Columb's Cathedral just around the corner, St Augustine's is tiny - hence the local name, The Wee Church on the Walls - but is pretty special. The site has been a religious place since St Columba (Colmcille) built his first monastery in 546AD - which has been generally accepted as the founding of the city. Various buildings have come and gone over the years - the present one dates to 1872.
Apparently the cannonball containing the terms for surrender during the Seige of 1688/89 fell in the Church Graveyard. It's fair to say there's a bit of history in this little spot.
