The University of Oñati was founded in 1540. Until its closure in 1901, it was the only university in the Spanish Basque Country. Its building is now the home of the International Institute for the Sociology of Law.
Founded in 1540 by the Bishop of Avila, Rodrigo Mercardo de Zuazola under the authority of a bull of Pope Paul III, the University of the Holy Spirit was originally located in Hernani, but in 1548 moved to Oñati. The University specialised in theology, law, canon law, the arts and medicine and was strictly limited to Catholics until 1869, when it was opened to all. The institution closed in 1901. Since 1989, the building houses the International Institute for Sociology of Law (IISL).
In 1931 the building was declared a National Historic Monument. It is one of the most remarkable Renaissance buildings of the Basque Country, and was built in the Plateresque style. Construction of the building began in 1543 by the master stone mason Domingo de la Carrera and the sculptor Pierre Picart.
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.
