The Dallas Dhu distillery was a producer of single malt Scotch whisky that operated between 1899 and 1983. Dallas Dhu means 'Black Water Valley' in Gaelic. Its whisky also appeared as a 'Dallas Mhor' single malt. In 1899, Alexander Edward designed the Dallas Dhu distillery at the height of the whisky boom. Later he sold the plans and the distillery was built by the blender Wright and Greg. It was acquired by Benmore Distilleries Ltd, which joined DCL in 1929. The stillhouse was destroyed by a fire in 1939, but rebuilt. Production continued until the distillery closed in 1983; it is now a museum.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
