The City Hall is located on the right bank of the Estuary of Bilbao across the Puente del Ayuntamiento bascule bridge that links it to the central Abando district.
The building was built in 1892 by Joaquín Rucoba, on the former site of a convent in the district of Uribarri. It was built in Baroque style. One of the highlights of the building is the Arab Hall, a richly decorated hall in the Neo-Mudéjar style that resembles the decorations found in the Alhambra of Granada. The hall is used for official receptions and weddings.
Before 1890, the city's council was located in a building inside the Old Town.
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.
