In this letter, we take a trip to Kutna Hora in the Czech Republic, a lovely and less touristy town one hour out of Prague. Step into history by visiting the haunting Sedlec Ossuary, a church elaborately decorated with human bones, and discover the grand architecture of St. Barbara's Church. Wandering the cobblestone streets and underground silver mines, the city is a hidden gem.

• The letter includes the envelope, a real stamp, the letter and a photo of the ossuary.
