To the east of the village, the remains of a medieval fortification can be found, characterized by its still visible moat system. The Gschlößl is a water castle from the early 13th century, consisting of three concentric moats and ramparts.
Observation Tower and Information Pavilion
The center of Gschlößl is of historical significance for the village of Leithaprodersdorf. There stood the water castle Leithaprodersdorf, where a court hearing took place in 1232, which is referred to in the first documentary mention of Leithaprodersdorf. A 10m high observation tower is intended to provide a better overview of this site. It was constructed by the company Seczer from Grub in the Wienerwald, as was the covering of the sarcophagi, which is meant to provide protection from precipitation. Additionally, two tombstones can be viewed, which were uncovered during excavation work by the Federal Monuments Office in the Rieden Keuzäcker and Bachreuth.
Children's Playground
In 2011, a new children's playground was built at Gschlößl next to the existing toboggan hill. Special attention was given to the wishes of the children. The concept was developed jointly by a dedicated working group as part of the village renewal process. A drinking water fountain was also installed.
