The Guggenheim Museum Bilbao is a museum of modern and contemporary art designed by Canadian-American architect Frank Gehry. The museum was inaugurated in 1997 by King Juan Carlos I of Spain, with an exhibition of 250 contemporary works of art. Built alongside the Nervion River, which runs through the city of Bilbao to the Cantabrian Sea, it is one of several museums belonging to the Solomon R. Guggenheim Foundation and features permanent and visiting exhibits of works by Spanish and international artists. It is one of the largest museums in Spain.
One of the most admired works of contemporary architecture, the building has been hailed as a 'signal moment in the architectural culture', because it represents 'one of those rare moments when critics, academics, and the general public were all completely united about something', according to architectural critic Paul Goldberger. The museum was the building most frequently named as one of the most important works completed since 1980 in the 2010 World Architecture Survey among architecture experts.
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.
