The castle of Mergentheim was the residence of the Grand Masters of German Teutonic Order from 1525-1809. In 1996 the museum was opened with around 3000 m² of exhibition space. The 800-year history of the German Teutonic Order from 1190 to the present day is illustrated with objects, works of art and models.
The castle has a rich architectural history. There are Romanesque structural elements (residential quarter covered footpaths), Renaissance (Berwart staircase), Rococo (gods room) and Classicism (chapter hall). The jewel of the residence is the castle church, for which artists such as Balthasar Neumann and François de Cuvilliès were called in to assist with the building.
The first buildings of the castle were probably erected as early as the 12th century. The castle was expanded in the late 16th century under Grand Master Walter von Cronberg. Over the course of time a representative Renaissance complex was built by connecting the individual buildings in the inner palace courtyard to a closed ring of buildings. In 1574, the main architect, Blasius Berwart, also constructed the spiral staircase between the west and north wing still famous today.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
