The Château de Greifenstein is a ruined castle in the commune of Saverne. The Grand-Greifenstein was, without doubt, founded in the first half of the 12th century by the knight Meribodo de Greifenstein who had close links to the Ochenstein family. The Petit-Greifenstein dates from the end of the 13th century or start of the 14th century.
Visitors can distinguish two castles separated by a large ditch. The older part has the largest keep in Alsace with 13 metres a side. A renovated tower stands between the two keeps at the centre of the site. It was probably part of Grand-Greifenstein. From the terrace there is an unimpeded view of Saverne, the Château du Haut-Barr, the Château du Grand-Geroldseck, the valley of the Zorn and the Saint-Vit chapel.
To reach the castle, leave Saverne on the D132 road towards Lutzelbourg and turn right towards the Ramsthal lake. Then follow the Club Vosgien path signposted by a blue rectangle.
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.
