Melk Abbey

Melk Abbey or Stift Melk is an Austrian Benedictine abbey, and one of the world's most famous monastic sites. It is located above the town of Melk on a rocky outcrop overlooking the river Danube in Lower Austria, adjoining the Wachau valley.

The abbey was founded in 1089 when Leopold II, Margrave of Austria gave one of his castles to Benedictine monks from Lambach Abbey. A monastic school, the Stiftsgymnasium Melk, was founded in the 12th century, and the monastic library soon became renowned for its extensive manuscript collection. The monastery's scriptorium was also a major site for the production of manuscripts. In the 15th century the abbey became the centre of the Melk Reform movement which reinvigorated the monastic life of Austria and Southern Germany. – wikipedia

Mauthausen Concentration Camp

Mauthausen Concentration Camp (known from the summer of 1940 as Mauthausen-Gusen Concentration Camp) grew to become a small group of Nazi concentration camps that was built around the villages of Mauthausen and Gusen in Upper Austria, roughly 20 kilometres (12 mi) east of the city of Linz.

In January 1945, the camps, directed from the central office in Mauthausen, contained roughly 85,000 inmates. The death toll remains unknown, although most sources place it between 122,766 and 320,000 for the entire complex. The camps formed one of the first massive concentration camp complexes in Nazi Germany, and were the last ones to be liberated by the Allies. The two main camps, Mauthausen and Gusen I, were labelled as "Grade III" (Stufe III) camps, which meant that they were intended to be the toughest camps for the "Incorrigible Political Enemies of the Reich". – wikipedia
