At the heart (and the soul) of Mengeš is St Michael's Parish Church and its accompanying grounds. What started off as romanesque became gothic which finally became baroque, complete with a 15th century gothic presbytery containing many frescoes painted by Janez Ljubljanski (a respected Slovene painter of the same century). Jože Plečnik also has his fingerprints all over it, with his plans forming the basis for the confessional boxes and baptistry inside. It can be argued that the church tower is responsible for Mengeš still standing in the form it does today. When Turkish war addicts were on the door in the 16th century, it was from here that the people of Mengeš were able to protect themselves from an almost certain violent death.
