The Counts of Rapperswil probably built a defense tower in the early 12th century on the site of today's Greifensee Castle. The beginnings of Greifensee Castle, which was partially destroyed in May 1444 (during the so-called Old Zürich War), date back to around 1250. The castle complex consisted of a Palas on a rock , which at the time stood directly on the lake shore and was protected on the other sides by a moat and ring wall. In 1520, the Zürich Council decided to rebuild the ruins to a modest castle.
After thorough renovation, the castle is now available to the public for conferences, seminars, lectures, presentations, receptions, courses, small concerts, exhibitions, cocktails and private events (banquets, weddings). You may also rent single rooms only.
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.
