During the centuries of German economic domination, the guilds were Riga's power brokers. The former, dating from 1384, was the home of the merchants, while the latter held the city's artisans. These slightly different audiences are reflected in the respective usage of the buildings today: while the Great Guild is home to the Latvian Symphony Orchestra, its smaller cousin hosts conferences and the occasional disco. The Small Guild is now also open to the public during the day for a small admission fee of 1Ls.
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.
