Church of St Havel Church (Kostel sv. Havla), Prague

St. Havel's Church was built between 1232 and 1239 in the Gothic style, but in the mid-17th century it was re-built in a more modern baroque style. As years passed, it became part of the Carmelite monastery until the late 18th century leader Joseph II reformed it to its present day look. Konrad Waldhauser and Jan Milic once preached here and the Church is now considered one of the four most important churches of its time.
