This is St. Patrick's Church in Cumberland, MD. The history of this church spans over 200 years beginning back in 1791. The church, as you see here, was completed in 1851 and was designed by Irish Architect Johm Tehan. You can read more about St. Patrick's Church at their website found here:
As for this photo, it was taken with a 5MP P&S camera. ISO would have been 50 but the exposure settings have been lost. However, from past experience, most likely it was at 1/500 sec @f/5.6 or 1/250 sec @f/8. In Photoshop Elements I cropped for the square look and then converted it to a B&W image. I did add a little dodging and burning and, after re-sizing, I added just a touch of sharpening. Finally I put a little green back into the photo in honor of St. Patrick's Day.
As for Saint Patrick, he was a Bishop in Ireland from 432 to 461AD when he died that year on March 17th; interesting, huh? It was also said of St. Patrick that he would use a Shamrock in explaining the Holy Trinity to those he was evangelizing. The three leaf plant stood for The Father, The Son and The Holy Spirit, and he was very successful in converting the rich and aristocratic, as well as the poor, to Christianity.
