As a day trip from Prague I caught the metro then a bus way out of the city to the unesco heritage town of Kutna Hora. Really, just a place stuffed full of old buildings- all charging admission for your eyes to gaze upon their innards. Actually, it felt more like any small town. Just happened to be there longer. May have been better to take the day tour but just wasn’t feeling like coughing up the 30 whatever euros for the day.
The giant round stone thing is an old fountain.
Lastly the major attraction: the bone church. After an attack on the church of of the monks “redecorated”. The bones serve as a reminder of our mortality- and the things creative ways monks pass the time. the chandelier is made using every bone in the body.
