The Frohberg ruin , also known as Tschäpperli or Tschöpperli , is a medieval castle ruin and is located in the Swiss municipality of Aesch im Birseck .
location
The ruins of the Höhenburg are located on a rocky ridge at the upper end of the Klusertal on the way over the old Plattenpass . It is located in the immediate vicinity of the Schalberg ruins , the Engenstein ruins and the Münchsberg ruins and, as the furthest ruin in the Aescher Klus, actually forms the beginning of the Aescher Burgengratweg.
history
The Frohberg Fortress was documented in 1292 when Konrad I. Schaler "de Vroberg" was named . It can be assumed that the castle was founded by the Schaler family in the 2nd half of the 13th century. Although the castle dominated the route over the Plattenpass (between Birseck and Laufental ): The choice of location in the immediate vicinity of other castles suggests that the motivation is not in the levying of tolls, but in power games between the Schaler and Münch families is looking for.
Werner Meyer notes that the castle may never have been completely completed: However, a reliable statement can only be obtained through a thorough excavation, because the castles were often continued to be built over a long period of time during their use. Carl Roth suspects that the castle was damaged and never repaired during the Basel earthquake of 1356. In any case, the remains were transferred to the Counts of Thierstein-Pfeffingen as an episcopal fief in the 14th century . Here, too, the interest is less likely to have come from the ruin - and with it considerable additional maintenance costs - but more from the goods and rights associated with the castle (tax collection, jurisdiction, etc.). The Thiersteiners integrated the goods into the Pfeffingen rule, which was administered from the nearby Pfeffingen ruins .
The original name 'Vroberg' has changed popularly in the course of time to Tschäpperli and Tschöpperli: This probably goes back to the field name of the same name that is still in use today for the rear end of the Klusertal, which was derived from the name 'Tschopp'.
investment
The castle ruin is extensive and consists of an extensive main castle surrounded by various obstacles to approach. So far, the ruins have not been archaeologically examined and secured, so that only rough interpretations are possible.
On the west and north side there is a deep, natural ditch (see picture), on the east side an artificial neck ditch and to the south there are ramparts and ditches. The latter are severely disturbed by agricultural tillage on the south and west sides.
The main castle was formed by a residential wing and Bering . The circular wall follows the irregularly running rock edge. The mighty residential wing consists of two parts, with a smaller west building with an irregular floor plan as a residential tower . The walls, which are up to three meters thick, were built from little machined blocks. Adjacent to the east of the residential wing, an elongated building for commercial and residential purposes is to be assumed. On the NW and NE sides, remains of Vorwerk are still visible.
According to Werner Meyer, access to the castle was on the north-west side of the fortress: Either via a ramp from the moat or over a bridge that was supported by a natural boulder (see picture) and enabled access from the edge of the moat. Based on Walther Merz, Carl Roth also keeps the possibility open that there could have been an access through the aforementioned Vorwerk on the east side.
