The Catholic part of the collegiate church of St. Aegidien had become too small for the growing number of Catholics in Neustadt/Weinstraße. King Ludwig I of Bavaria (1786-1868) made the new building possible with a generous donation. Vincenz Statz, who in 1845 was the second foreman of the Cologne Cathedral, created the blueprint for the church . The Catholic community in Neustadt/Weinstraße has since the founding of the Marienkirche been celebrating their Mass here. As a church in the centre of our city, it is visited daily by many people for prayer. The neo-Gothic furnishings of the church have been largely preserved to this day. War damage and the lowered groundwater level have necessitated extensive renovation and reinforcement work during the recent decades. In connection with the modifications did the Marienkirche receive new artistically designed windows between 1962 and 1974, mainly with scenes from the life of Mary.
