The Irish missionary monk Havel (550 - 640), was famous for his sensitive attitude to people, the desire to help and comfort. He zealously preached the Christian faith and allegedly knew how to cast out demons. The church, which has been located in the Old Town since time immemorial, is named after him. The first mention of the church of St. Havel dates back to the thirties of the XIII century. It is important for the whole history of Prague because the so-called Havel City was formed around the church during these years, which later merged with the Old.→
