Neuschwanstein was an enstatite chondrite (type EL6) meteorite that fell to Earth on 6 April 2002 at 22:20:18 GMT near Neuschwanstein Castle, Bavaria, at the Germany-Austria border. The original meteorite burst into several fragments at a height of about 22 kilometers (14 miles) above the ground. The fragments descended on an area of several square kilometers. Three fragments were recovered with a total mass of about . Neuschwanstein was the first meteorite in Germany, and the fourth in the world, that was monitored by one of the world's fireball networks, namely by the European Fireball Network. Photographing the meteor simultaneously from several locations allowed accurate reconstruction of its trajectory.〔〔 == Meteorite fall == The trace of the Neuschwanstein meteor within the Earth's atmosphere began at a height of about , about east-northeast of Innsbruck, with an entry angle of about 49° to the horizontal, and ended above the Earth's surface. Shortly before that it split into fragments at the "endpoint" at a height of about .〔 The entry velocity of in the atmosphere was rapidly reduced by air resistance to about at the end of the visible trajectory. Then the meteorite went into free fall which lasted about 108 seconds. The impact velocity on the surface was about . The fragments were displaced in the lower atmosphere (troposphere) from their expected trajectories by strong wind.〔 The European Fireball Network monitored the meteor from several stations, including those in Augsburg (Germany), Přimda (Czech Republic) and Weyregg am Attersee (Austria). Simultaneous observation allowed accurate reconstruction of the flight path using triangulation.〔 〕 Neuschwanstein was the first meteorite in Germany and the fourth meteorite in the world that was monitored by one of the several world's fireball networks, after Príbram meteorite of Czechoslovakia in 1959; Oklahoma in 1970 and Canada in 1977.〔 File: NSSTriang1en.jpg|3D triangulation of the atmospheric trajectory of Neuschwanstein by the European Fireball Network stations.
