Irnharting Castle is two kilometers west of Gunskirchen.
The castle consisting of two parts was built in a large square pond on two islands in it. The front chateau with the tower was connected to the rear building by a bridge. The buildings on the front island were grouped around a courtyard that was open on one side, namely the one that faced the other island with its castle building. Located on the former front island, the complex is a three-wing structure.
The tower, the base of which has been converted into a gate hall, stands almost in the middle of the front wing and is still the only entrance to the palace today, since the pond in the form of a wide, water-bearing ditch has been preserved here. A brick bridge spans the moat in front of the gate tower.
The second castle complex, formerly also a horseshoe-shaped complex, was closed and covered by modifications and is now the actual inhabited castle. The drained pond floor is significantly lower than the level of the former islands and the adjacent corridors, but the grassy ground is continuous wet and even swampy in places.
