The House of Soviets is a building located in the city of Kaliningrad and was built on the original territory of Königsberg Castle. The castle was severely damaged during the bombing of Königsberg in World War II. Following the war, as the city came under the control of the USSR, the site of the castle was redeveloped as part of the reconstruction of the city. Construction began on the House of Soviets in 1960, and was intended to be the central administration building of the Kaliningrad Oblast.
Continuation of development was stopped in the 1980s after the Regional Party Committee lost interest in the project and cut off funding. The building was left unfinished for many years, and earned notoriety as one on the worst examples of post-war Soviet architecture.
In 2005, for a visit by President Vladimir Putin, the exterior was painted light blue and windows were installed. However, the interior remains unfinished and unusable. A German consultant has recommended tearing down the entire structure and building anew as cheaper and safer than attempting to repair and finish the existing shell.
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.
