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:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
