Lower Castle / Alt-Schellenberg Castle
The Lower Castle, colloquially also called Alt-Schellenberg Castle, is a castle ruin. The Lower Castle is one of the five existing castles in Liechtenstein and one of the three castle ruins in the country.
The Lower Castle is the smaller and newer of the two castle ruins in the municipality of Schellenberg. Construction was completed around 1250. The first written mention dates from 1317. The castle reached its peak in construction around 1350. According to current estimates, it was inhabited until around the 16th century, when it was abandoned and no longer served as a residence. In the following centuries, the castle lost its military purpose and became a ruin.
In 1956, Prince Franz Joseph II of Liechtenstein handed over ownership of the heavily overgrown ruin to the Historical Association for the Principality of Liechtenstein. This institution is the current owner and caretaker of the ruin and oversees its research, maintenance and preservation.

Smaller than the other ruins, but also definitely worth seeing, especially the bread oven.
