It can be interesting to look into differing beliefs. An outing to Kazan Church is an excellent way to deepen your understanding of one of the local religions.
You'll soon see why this Uglich house of prayer is visited by many travelers. If you're looking for more to do and see here, Church of St John Chrysostom Nativity, St Nicholas' Church, and Epiphany Convent of Uglich are in the area as well. They won't take you very long to reach from Kazan Church.
