The Deutsches Museum is the world's largest museum of science and technology, with approximately 1.5 million visitors per year and about 28,000 exhibited objects from 50 fields of science and technology.
The museum was founded on June 28, 1903, at a meeting of the Association of German Engineers as an initiative of Oskar von Miller. The main site of the Deutsches Museum is a small island in the Isar river, which had been used for rafting wood since the Middle Ages. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher. In 1944, near the end of the war, the building was hit by numerous air strikes. More than 80% of the structure was destroyed.
This amazing attraction is the largest technological museum of its kind in the world and is renowned for its incredible historic artifacts, which mark important steps in the field of science and technology. Exhibits at the Deutsches Museum are many and varied and cover topics such as aerospace, astronomy, agriculture, computers, chemistry, electricity, marine navigation, mining, music, railways, and telecommunication.
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.
