St. Catherine's Church is one of the five principal Lutheran churches of Hamburg. The base of its spire, dating from the 13th century, is the second oldest building preserved in the city, after the lighthouse on Neuwerk island. It is situated on an island near what was formerly the southern boundary of the medieval city, opposite the historic harbour area on the Elbe river. It traditionally served as the church of the seamen.
The earliest attestation to the existence of the church dates back to 1256. The main body, consisting of a triple nave, was rebuilt during the mid-15th century in the north German Brick Gothic style. In 1657 a Baroque rooftop was added to the spire, which thus reached a height of 115 meters. The church was heavily damaged in an air-raid during World War II, on 30 July 1943. It left only the outer walls and the base of the spire standing. The building was restored between 1950 and 1957.
St. Catherine's had an organ as early as the late 15th century, and by the 16th century it was considered the most important in Hamburg. This organ was replaced by a new organ built by Hans Stellwagen, rebuilt in 1670 and repaired by Johann Friederich Besser. In 1720, according to Johann Mattheson, this organ consisted of some 58 stops and approximately 88 ranks which may have made it the largest organ in the world at that time.
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.
