This year St Ann's parish, Dublin, will celebrate its tercentenary and to mark this milestone a number of special events will take place.
The celebrations will begin tomorrow with a service on RTÉ 1 during which the address will be given by Canon Jack Black, former headmaster of Kilkenny College and a curate in St Ann's from 1968 to 1973.
Subsequent events will include a parish think-in in the spring, a dinner and harvest thanksgiving reunion service in the autumn and a songs of praise evening in November.
When the parish was founded in 1707, Dawson Street was a rural part of Dublin and the church was known as "St Ann's in the Cornfields."
A downtown parish, its focus is on outreach to the community passing its doors everyday.
The description, "the church in the heart of the city with the city at its heart," is more appropriate for these times.
Over the years many people have found a spiritual home in St Ann's. Amongst famous names associated with the parish are Wolfe Tone, Bram Stoker, Hugh Lane and Dr Barnardo, while those from more recent times include Douglas Hyde and Erskine Childers.
As a city centre parish, members of the congregation were often transient as they were in Dublin studying at one of the educational institutions in the city. Other young people lived in the GFS, the YWCA or the Harding Boys' Home until they became established in business or married and returned to the country.
Great efforts have been made by the tercentenary committee to contact former choristers, parishioners, and others associated with the parish to let them know of these events, but inevitably some people will be left out.
