It's often interesting to explore differing beliefs. An outing to St. Francis de Sales Catholic Church is an excellent way to get to know a part of the local way of life.
You're spoiled for sightseeing choice when in Paducah. St. Francis de Sales Catholic Church is a good place to begin here, but there are many other worthwhile spots to experience. National Quilt Museum, Kentucky Oaks Mall, and Luther F. Carson Four Rivers Center are near the house of prayer and will round out your day nicely.
