Basilica of St. Francis (Bazylika Św. Franciszka)
St. Francis' BasilicaThe interior of this church is stunning, the exact opposite of what you’d be led to believe if you simply glanced at the simple brick exterior. The interior features art nouveau inspired designs of flowers, geometric shapes, and interesting floral and nature inspired patterns. Every square inch of the walls are covered with paint, and even if you've been inside hundreds of European churches, you could definitely spend time inside this one admiring its beauty. Don't forget to peek inside the chapel to see a perfect replica of the Shroud of Turin.
