The Albert Memorial Clock was completed in 1869 and is one of the best known landmarks of Belfast. It was built as a memorial to Queen Victoria's late Prince Consort, Prince Albert. The sandstone memorial was constructed between 1865 and 1869 by Fitzpatrick Brothers builders and stands 113 feet tall in a mix of French and Italian Gothic styles. The base of the tower features flying buttresses with heraldic lions. A statue of the Prince in the robes of a Knight of the Garter stands on the western side of the tower. A two tonne bell is housed in the tower and the clock was made by Francis Moore of High Street, Belfast.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.
