The Palace of Culture and Science is the tallest building in Poland and the eighth tallest building in the European Union. It is 231 metres tall, which includes a 43-metre high spire.
The building was originally known as the Joseph Stalin Palace of Culture and Science, but in the wake of destalinization the dedication to Stalin was revoked. The building was conceived as a 'gift from the Soviet people to the Polish nation', and was completed in 1955. The structure was built in three years according to the design of the Soviet architect Lev Rudnev. Architecturally, it is a mix of Stalinist architecture, also known as Socialist Classicism, and Polish historicism inspired by American art deco skyscrapers. Currently it is the headquarters of many companies and public institutions, such as cinemas, theaters, libraries, sports clubs, universities, scientific institutions and authorities of the Polish Academy of Sciences.
The tower was constructed, using Soviet plans, almost entirely by 3500 workers from the Soviet Union, of whom 16 died in accidents during the construction.
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.
