The original Allmendingen Castle was built during the High Middle Ages probably for the Lords of Allmendingen or Alwandingen. Between 1239 and 1256 Rudolf von Alwandingen was mentioned in the record. In 1256 the Lords of Allmendingen sold both Allmendingen and the neighboring hamlet of Märchligen to Interlaken Abbey. The castle fell into disrepair and during the 16th century the cartographer Thomas Schöpf referred to it as a arx disruta or broken castle. In 1676 Albrecht Kauws mentioned the ruins of Alt-Allmendingen Castle and by 1729 the ruins were still visible. The old castle had walls that were about 2.1 meters and was a square with 9 meters long walls. The south and west side had no windows.
After the Protestant Reformation in 1528, Interlaken Abbey was secularized and its lands, including Allmendingen, were taken by Bern. A new Allmendingen Castle was built near the old castle during the 16th or 17th century. One clue as to the construction date is that a door in the tower bears the year 1607. The new castle was built for the Graffenried family in the Renaissance style. The tower was initially topped with a high pointed roof, which was later replaced with a lower one. In the 18th century, the castle was renovated by the Schultheiss Isaak Steiger and then by his son Franz Ludwig. They expanded the castle with a garden court yard and a connecting arbor.
On 17 September 1946 Winston Churchill visited Allmendingen Castle.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
