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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
