Funnily enough, though the tour of this church is called “Catacombs by Candlelight”, the catacombs aren’t the highlight of this sweep through the Old St. Patrick’s Cathedral. What makes this experience so absorbing is how the talented, humorous guides retell the history of the city—and country—through the lens of Catholic immigration. Visitors are on the move while this happens. Over the course of the tour, you’ll roam through a historic graveyard, into the church sanctuary, into side rooms of the structure, and yes, into the dimly lit burial place below what had been the city’s first cathedral.
