The ruin Frohnberg, also Tschäpperli or Tschöpperli, is a medieval castle located in the Swiss community in Aesch Birseck.

Location

The ruin is situated on a rocky ridge at the top of Klusertales on the trail over the old disk password. It is located near the Ruin Schalberg, the ruins of plutonic rock and the ruins Munchberg and forms as rearmost ruin in the Aescher Klus actually the beginning of the Aescher Burgengratweges.

History

Documented the festivities Frohnberg was in 1292 with the entry of Conrad I Schaler " de Vroberg ". It is believed that the castle was founded by the family of the bivalves in the second half of the 13th century. Although the castle dominated the way across the board Pass ( between Birseck and Laufental ): The admission in the immediate vicinity of other castles, however, suggests that the motivation not to be in the collection of Wegzöllen, but in power games between the families of bivalves and Münch is looking for.

Werner Meyer notes that the castle was possibly never quite completed: a safe statement is to win but only by a thorough excavation, because often was further built the castles over long periods of time during use. Carl Roth believed that the castle was damaged during the Basel earthquake of 1356 and not repaired. In any case, the remains were a 14th-century bishop's fief of the Counts of Thierstein - Pfeffingen. It is likely less of the ruins here also the interest - be considered but especially of the castle with the related assets and rights ( tax collection, justice, etc.) - and thus considerable extra costs of maintenance. The Thiersteiner integrated the equipment into the reign Pfeffingen, which was managed by the nearby ruins of Pfeffingen.

The original name, Vroberg ' has changed over time in the vernacular in Tschäpperli and Tschöpperli: This probably goes back to the still in use today, the same field names for the rear end of the Klusertales, by the name, Tschopp ' was derived.

Plant

The ruins are extensive and consists of an extended main castle, surrounded by various approximation obstacles. Until now, the ruin was but not yet archaeologically investigated and secured so that only rough interpretations are possible.

On the western and northern side there is a deeper, more natural trench is located (see picture), on the east side of an artificial moat and towards the south upstream ramparts and ditches. The latter are strongly disturbed by agricultural tillage on the south and west side.

The main castle was formed by a housing tract and Bering. The curtain wall follows the irregular running rock edge. The massive living area consists of two parts, with a smaller West building with an irregular floor plan tower house. The up to 3 meters thick walls were built of little processed blocks. To the east adjoining the living area is an elongated, commercial and residential purposes serving building to suspect. On the NW and NE side remains of ramparts are still visible.

Access to the castle was carried out by Werner Meyer on the north -west side of the fortress: either via a ramp from the ditch or over a bridge (see picture) supported by a natural boulder, enabled by the grave edge of the access. Carl Roth keeps - having regard to Walther Merz - open the possibility that there may have been on the east side access through said Vorwerk.
