Catholic Churches always have stained glass windows in them. Back in Gothic times, before people were educated, this was a way of teaching Bible stories to people. Each window tells of one of these stories. Also in the church are the stations of the cross. St. Mary's has received tapestries of the 15 stations of the cross.
Most churches use statues.
All of the tapestries are hand-stitched and imported from Italy. There is also a book that has been published to commemorate the centennial.
