A free 45-minute tour of its splendid art, architecture and history at a time we're decorated for Christmas. This is a unique opportunity for the community to see and hear what impressed the Vatican so much that Pope Francis designated this local church a Basilica. Our remarkable history began in 1850 here on this very lot in Olean. Learn unique aspects about our art and architecture as you experience the beauty and scale of the basilica's famous Munich-style windows (as large as 20 feet tall) and hear about the development of the opulent interior decoration that includes original art spanning back to the 19th century. Our spectacular windows are 100 years old this year! Come to enjoy them with sunlight shining through on the day after Christmas, St. Stephen's Day!
