The Old Synagogue in Dubrovnik is the oldest Sefardic synagogue still in use today in the world and the second oldest synagogue in Europe. It is said to have been established in 1352, but gained legal status in the city in 1408. Owned by the local Jewish community, the main floor still functions as a place of worship for Holy days and special occasions, but is now mainly a city museum which hosts numerous Jewish ritual items and centuries-old artifacts.
Located in one of the many tiny streets of the Old Town of Dubrovnik, it is connected to a neighboring building which has long been owned by the Tolentino family, who have been caretakers of the synagogue for centuries. The internal layout is different from other European synagogues and has gone numerous refurbishments throughout the centuries, and has a mixture of designs from different eras. The building has sustained damage several times, with the great earthquake in 1667, World War II, and the Croatian War of Independence in the 1990s. The damage has since been repaired as closely as possible to its original design.
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.
