The Venetian Ghetto was the area of Venice in which Jews were compelled to live under the Venetian Republic. The English word 'ghetto' is derived from the Jewish ghetto in Venice, originating from the Venetian ghèto and Italian ghetto.
The Venetian Ghetto was instituted on 29 March 1516, though political restrictions on Jewish rights and residences existed before that date. In 1797 the French army of Italy, commanded by the 28-year-old General Napoleon Bonaparte, conquered Venice, dissolved the Venetian republic, and ended the ghetto's separation from the city. In the 19th century, the ghetto was renamed the Contrada dell'unione.
The Ghetto is an area of the Cannaregio sestiere of Venice, divided into the Ghetto Nuovo ('New Ghetto'), and the adjacent Ghetto Vecchio ('Old Ghetto'). These names of the ghetto sections are misleading, as they refer to an older and newer site at the time of their use by the foundries: in terms of Jewish residence, the Ghetto Nuovo is actually older than the Ghetto Vecchio.
Today, the Ghetto is still a center of Jewish life in the city. The Jewish Community of Venice. There is also a yeshiva, several Judaica shops, and a Chabad synagogue run by Chabad of Venice. Although only few of the roughly 500 Venetian Jews still live in the Ghetto, many return there during the day for religious services in the two synagogues which are still used (the other three are only used for guided tours, offered by the Jewish Community Museum).
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
