The Arnstein Castle was first mentioned in writing in 1170. The first castellan and builder of the complex was Wichard von Arnstein, who was the feudal lord of Hohen Lindkogel and Peilstein at that time. The von Arnstein family owned the castle until the 14th century.

The Antonsgrotte opposite the Cholera Chapel in Helenental is a popular destination. The place of worship, always decorated with candles, now has another attraction. Bird feeding is carried out there with particular passion, and indeed: the birds eat a lot and happily. BADEN. Bird feeding at the Antonsgrotte is a tradition. Elisabeth Werkmann - she has been looking after the Antonsgrotte for five years - took over this task last year from her predecessor, who suddenly dropped out.

On the 561 meter high Arnstein, in the dense forest, you can discover the remains of Arnstein Castle, which was built in the 12th century. After it was destroyed during the Turkish siege in 1529, the complex was partially rebuilt and changed hands several times. Since 1955, the ruins have been managed by the Austrian Federal Forests. A detour to the Arnsteinnadel rock formation is also worthwhile.

The network of promenades dates back to Archduke Anton (1779–1835), who had it built in the years up to 1829. The highlight was the Antonsgrotte, which stands roughly opposite the Cholera Chapel, which did not yet exist at the time. The approximately 2.2 km long section of the Helenental from Antonsbrücke to Antonsgrotte is therefore called Antonstal. Source: https://de.m.wikipedia.org/wiki/Helenental

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.
