St. Catherine's Church in Middelhagen, with boulder foundations, was built around 1455. The wooden tower was created only later – according to the strict rules of the Cistercian monks, many churches were built without towers. The Catherine's altar from the Middle Ages (c.1480) is still preserved – it was probably installed here only after the Thirty Years' War, having been brought from Stralsund to Middelhagen. Another very valuable piece is a chalice dating from 1597; it is made of gilded silver.
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.
