Saint Adalbert Basilica, (referred to in Polish as Bazylika Swietego Wojciecha) is a historic Roman Catholic church located on Buffalo, New York's East Side within the Diocese of Buffalo. It is a prime example of the Polish Cathedral style of church architecture in both its opulence and grand scale. A rare and special designation bestowed on the parish occurred in 1907, when the Vatican proclaimed St. Adalbert a basilica, the first in the USA. The proclamation, as well as its English translation, can be viewed to this day in the basilica's museum room.
