The Old New Synagogue (Staronová synagoga) situated in Josefov, Prague, is Europe's oldest active synagogue. It is also the oldest surviving medieval synagogue of twin-nave design. Completed in 1270 in gothic style, it was one of Prague's first gothic buildings.
An unusual feature found in the nave of this synagogue is a large red flag near the west pillar. In the centre of the flag is a Star of David and in the centre of the star is a hat in the style typically worn by Jews of the 15th century. Both the hat and star are stitched in gold. Also stitched in gold is the text of Shema Yisrael. Ferdinand III, Holy Roman Emperor awarded the Jewish community their own banner in recognition for their services in the defence of Prague during the Thirty Years War. The banner now on display is a modern reproduction.
It is said that the body of Golem (created by Rabbi Judah Loew ben Bezalel) lies in the attic where the genizah of Prague's community is kept. A legend is told of a Nazi agent during World War II broaching the genizah, but who perished instead. In the event, the Gestapo apparently did not enter the attic during the war, and the building was spared during the Nazis' destruction of synagogues. The lowest three meters of the stairs leading to the attic from the outside have been removed and the attic is not open to the general public.
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.
