Let me introduce the whole town here. Kutnahora, a medieval city, has a glorious past, and it was once a very rich and important city because it was the most important silver mine in the Bohemian kingdom. The most attractive thing to tourists in the city is the Bone Church, which has become almost a masterpiece of human bone art taken from the Black Death. But in fact, the city's silver miner guardian Santa Barbara named the cathedral is its true architectural art hall, and it is a cathedral built for more than 500 years.
