After his death, the giant Einöder was carried away into the Anninger. To this day, he lives deep within the Einödhöhle and is considered by the people to be the most powerful guardian of the land against the incursions of enemy armies from the east.

The Matterhörndl is a small but impressive rock in the Vienna Woods that is perfect for a short rest. It is a little hidden away from the main path and easy to miss, but it is worth the visit. With a small opening through and the opportunity to climb around a bit, it is a mystical place for photographers, children and nature lovers. I visited this mountain as part of my Dwarf Mountain Tours series. My goal is to climb every mountain in the Vienna Woods.

10/02/2022 - Near the former Rauheneck Castle, which together with the Rauhenstein controlled the entrance to the picturesque Helenental near Baden, lies the bizarre royal cave, which was already inhabited in the Neolithic Age (2200 to 1800 BC). Archaeological excavations made such important finds that the entire period is called the "Baden culture". The presence of humans in the La Tène and Hallstatt periods has also been proven; individual finds date from Roman times and the Middle Ages. Just listing the scientific publications about the cave fills a whole book page. It is not surprising that there are many legends about the cave. King Bela IV of Hungary is said to have sought refuge there, and there are also reports of evil dwarves and wild people. Here and there, the royal cave still serves as a bivouac site, as some traces in the natural monument show.

10/02/2022 - Now in autumn towards the evening there is an unreal atmosphere in the cave, in the dull evening light, in the leafless forest, hardly any colors can be seen here. I enjoy it, take my time taking photos and then climb around the hole in the ceiling above the cave. Great insights and views are the reward.
