We saw several fortified churches in Transylvania. When visiting the castle-church of Heltau/Cisnadie we got a tour guide, who gave detailed information about the castle church. Apparently this fortified structure gave great security to few families (around 150) in the area. The church still has a Sunday service and also occasional concerts. When we climbed the tower of the church --through narrow dark passages-- we had great views of Heltau. One could have a close view of the sonorous bells and also could hear the ticking of the huge Swiss-made clock, that still functions accurately.
We visited another church called Michelsberg castle on a hill. It required climbing up many stairs, which gave us very good exercise. This church was in a state of disrepair. The local community had set up a way to charge an entrance fee to the church, but it seemed to require bigger funds to completely renovate the place. UNESCO apparently supports some fortified churches, but not this one.
It is always helpful to find a guide (who are available there) to get the best out of the fortified church visit.
