While in Prague, we took a day trip out to the town of Kutná Hora. It was a simple train ride away!
A little background information. Kutná Hora was previously a mining town. The city has now been declared a UNESCO World Heritage site because of several buildings there.
And here are some of the places I visited.
First up was Sedlec Ossuary. I unfortunately can't find the photos I took of the interior! (Do a google search!) But its a Roman Catholic church that contains up to 70,000 skeletons. While a little daunting to be inside, it's definitely worth a visit.
However, I did manage to find a picture I took of the cemetery behind the church.
