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 Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
