Marzoll Castle was originally only two-story. From 1527 to 1536 it was rebuilt and extended by the Reichenhaller patrician family Fröschl and transformed into a Renaissance palace. By owning salt boilers in Reichenhall, the Fröschl had gained their enormous fortune. The family seat was designed in the Renaissance style that was new at the time and came from Italy. The facility in the form of a cubic structure with four round corner towers was the first of its kind in Bavaria. In the course of the 16th century the gate and the curtain wall were added. Under the lords of the palace from 1605–1798, the Barons Lasser von Lasseregg from Salzburg, additional outbuildings were built in 1708 and around 1750 the rooms on the second floor were decorated with stucco. The stucco work comes from Benedikt Zöpf, who also decorated the church of St. Valentine next to the castle in rococo style at this time. (Zöpf stuccoed several sacred interiors in Salzburg, including the collegiate church of St. Peter). From 1798 the barons of Laßberg zu Marzoll followed as owners by inheritance. In 1833 Marzoll was finally auctioned due to high debt and came to the Baron von Aretin. This finally passed the property on in Kaufweg to Erasmus Freiherrn von Malsen. Erasmus was president of the royal Bavarian Parliament in Munich and his wife Therese nee Freiin von Ruffin, lady-in-waiting to the Queen. He had the exterior of the castle redesigned from 1837. The Renaissance domes (Welsche hoods) of the four corner towers were removed and replaced by battlements in the neo-Gothic style. A crenellated wreath was built on the outer walls of the main building. (Compare Hohenschwangau Castle and Possenhofen Castle) From 1951 to 1991 the Barons von Ritter zu Groenesteyn, descendants of the Marzoll line of Barons von Malsen, lived in the castle before it passed into the possession of the City of Bad Reichenhall. Since then, the exterior has been renovated and the interior has been secured. The castle courtyard is open during the day, the interiors are only accessible as part of a guided tour.
In 2007 the castle was sold to two investors, Nico Forster and Alfons Aigner, who were planning to set up an Art Deco hotel and a private apartment in the castle. Nico Forster finally took over all the shares. After Forster's death in February 2010, the castle fell to his then minor heirs and the planned work was not continued (as of 2019)
