The metropolitan city of Kraków, former capital of Poland, is known as the city of churches. The abundance of landmark, historic Roman Catholic churches along with the plenitude of monasteries and convents earned the city a countrywide reputation as the "Northern Rome" in the past. The churches of Kraków comprise over 120 Roman Catholic places of worship, of which over 60 were built in the 20th century. They remain the centers of religious life for the local population and are attended regularly, while some are often crowded on Sundays.
