The Freibergsee is located at an altitude of 930 meters. With a water surface of around 16 hectares, it is the largest high mountain lake in the Allgäu. The Freibergsee has no visible inflows or outflows. Its periodically fluctuating water level is regulated by underground inflows and outflows. The lake was formed during the ice ages when the ice masses of the Stillach glacier towered 700 to 800 meters high above the current location.

The interior design of Neuschwanstein Castle features the recurring element of the soaring swan. This symbolizes purity and is the heraldic animal of the Counts of Schwangau, to which Ludwig II belonged. This bird can be seen everywhere, on the faucets, stained-glass windows, and even on the roof of the royal carriage.
