The monument has two names – both used: “St. Mary monument” and “St. Nepomuk monument". Both are (and were) correct, but could cause confusion: there was another “Mary”, quite famous, and it is in the namesake square from Iosefin, and there is also another Nepomuk near the Millennium Church in Fabric.
