The Château du Hohlandsbourg is a ruined castle Wintzenheim, near Colmar. The construction of the castle, on the order of the Provost of Colmar, Siegfried de Gundolsheim, dates from 1279. The site, 620 m above sea level, allowed for surveillance of Colmar and its region. In 1281, the townspeople of Colmar revolted and set fire to the castle with the help of the Bailiff, Otton d'Ochenstein.
The castle came under the control of the Ensisheims before being given in 1410 as a fiefdom to the Ribeaupierres, then Counts of Lupfen, who enlarged it. In the 16th century, the castle belonged to Lazarus von Schwendi, general of the Holy Roman Empire, who, it is said, brought Tokay vines from Hungary to Alsace. He enlarged and strengthened the castle.
With Alsace becoming French at the end of the Thirty Years' War, the castle welcomed troops who blew it up in 1637 to prevent it falling into the hands of an Austrian army.
Today Hohlandsbourg Castle offers a magnificent all-round panorama over the plain of Alsace and the Vosges Mountains. It is open to in summer season.
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.
