Not to miss
The greatest attraction is of course our engaged couple. The second best one than the mining towers.
You should definitely visit the leaning church of St. Peter from Alkantra in Karviná-Doly. The church has sank by 37 metres and leaned by 6,8° to the south (for comparison The Leaning Tower in Pisa before reconstruction leaned only by 5.5°). The holy mass here takes place regularly every sunday at 9:30. We were even considering having our wedding there, but Pavel decided that we want to start straight.
If you do have time, visit the spa. The new one is not as nice as the old one. Their building are mostly too modern and ugly. On the other hand you can profit from various procedures, e.g. polarium, massages, baths, etc. See the link.
