Check out the SALT MINE and the MOSAIC MUSEUM as well as some churches with unique interiors.

There was some subtle music/sound in this salt mine as well as this visual treat. Walking through the space was actually spiritual and calming.

The mosaic museum had well laid out mosaics and a few replicas. Really well done displays.
