Over the years I’ve visited more than two dozen St. Patrick’s churches in four countries, as detailed in this special section. But one historic church eluded me until earlier this month, when I finally stepped inside the Basilica of Old St. Patrick’s Cathedral in Lower Manhattan.

As the first church in the United States dedicated to Ireland’s patron saint, it was the original cathedral of the Diocese of New York. The cornerstone was laid in 1809, and the completed church was consecrated in 1815. St. Pat’s became a target of the Know Nothings and other anti-Catholic and nativist movements. Damage from an 1866 fire was repaired two years later. By then, however, construction had begun on the larger and now more familiar St. Patrick’s Cathedral on Fifth Avenue in Midtown Manhattan. Read more history of the first St. Patrick’s.

My wife and I attended the midday Mass at Old St. Pat’s during our recent visit. Here are a few photos:
