The Hôtel van Eetvelde is a town house designed in 1895 by Victor Horta for Edmond van Eetvelde, administrator of Congo Free State. Together with the Hôtel Tassel, the Hôtel Solvay and his own House and atelier it was put on the "UNESCO World Heritage List" in 2000 as the core of epoch-making urban residences Victor Horta designed before 1900.
The visible application of 'industrial' materials such as steel and glass was a novel for prestigious private dwellings at the time. In the Hôtel van Eetvelde Horta also used a hanging steel construction for the façade. The interior receives additional lighting through a central reception room covered by a stained-glass cupola. An extension to the house was designed by Horta in 1898. This building has a more conventional, beautifully detailed sandstone façade. It was designed to house a garage, an office for van Eetvelde as well as supporting apartments and therefore had a separate entrance.
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.
