The Budapest opera house is a beautiful Neo-Renaissance building opened in 1884. Construction included the use of marble and frescos by some of the best artisans of that era. Designed by Miklós Ybl, one of Europe's leading architects in the mid to late 19th century, the Budapest Opera House quickly became one of the most prestigious musical institutions in Europe. Many important artists performed here, including Gustav Mahler, who was also the director for three seasons.
The Budapest Opera House is considered to be amongst the best opera houses in the world in terms of its acoustics, and has an auditorium that seats 1200 people. It is horseshoe-shaped and, according to measurements done by a group of international engineers, has the third best acoustics amongst similar European venues (after the Scala in Milan and the Paris Opera House). The statue of Ferenc Erkel stands in front of the Opera House. He was the composer of the Hungarian national anthem and the first music director of the Opera. The other statue in front of the Budapest Opera is of Ferenc Liszt, the well-known Hungarian composer.
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.
