Built at the beginning of the 18th century, it boasts many outstanding features, such as the Renatus Harris built organ and spectacular stained glass window.St. Mary’s closed in 1964 and lay derelict for a number of years until it was purchased by John Keating in 1997. Following extensive restoration over a seven year period, this List 1 building finally re-opened its doors in December 2005 as John M. Keating’s Bar.
