The Sedlec Ossuary, which is an easy walk from the train station, is a morbid fascination and an absolute delight for those with macabre tendencies. Having just written poems on the mouth, I was particularly drawn to the jawbones and teeth (or lack of teeth). It's so rare to see what lies beneath all our flesh. The church is unfortunately rather small, but the amount of bones housed within the structure is pretty dazzling and the bones photographed beautifully.
There are two, maybe three, other churches within walking distance and they offer a special deal if you go to all of them, but as Justin and I were on our way to Budapest, we didn't visit. Perhaps another trip.
