We are seeing history that long out dates the United States as a country (even the slightest idea of the United States) by several hundred years. This cathedral is the oldest cathedral in all of Poland. It was build around 968 AD. For reference, this was before Leif Eriksson discovered North America.
We walked across town to this cathedral on All Saints Day (Nov 1) and prayed there. In one of the side rooms of the sanctuary, the ceiling had been recovered / preserved with the original fresco that was painted on it around the time of it being built. A 1000 year old painted ceiling, astounding.
