Predigerkirche is one of the four main churches of the old town of Zürich. First built in 1231 as a Romanesque church of the then Dominican Predigerkloster, the Basilica was converted in the first half of the 14th century, the choir between 1308 and 1350 rebuilt, and an for that time unusual high bell tower was built, regarded as most high Gothic edifice in Zürich.
The abbey-choir building had been used for secular purposes since the 16th century Protestant Reformation, and was transformed by the installation of shelves into a warehouse building. For several centuries it was used as a granary. Since 1914 the choir building has been administrated by the Zentralbibliothek (Zürich central library), the main library of both the canton, city and the University of Zürich.References:
The Erfurt Synagogue was built c. 1094. It is thought to be the oldest synagogue building still standing in Europe. Thanks to the extensive preservation of the original structure, it has a special place in the history of art and architecture and is among the most impressive and highly rated architectural monuments in Erfurt and Thuringia. The synagogue was constructed during the Middle Ages on the via regia, one of the major European trade routes, at the heart of the historical old quarter very close to the Merchants Bridge and the town hall. Many parts of the structure still remain today, including all four thick outer walls, the Romanesque gemel window, the Gothic rose window and the entrance to the synagogue room.
After extensive restoration, the building was reopened in 2009. On display in the exhibition rooms is an collection of medieval treasures discovered during archaeological excavations. This includes 3,140 silver coins, 14 silver ingots, approx. 6,000 works of goldsmithery from the 13th and 14th centuries and an intricately worked wedding ring of the period, of which only two others are known to exist anywhere in the world. A mikveh (Jewish bath) has been excavated close by (13th/14th century). The Old Synagogue, the Small Synagogue and two Jewish cemeteries together form a network of historical buildings and sites which vividly portray the role of Jewish life in the history of Erfurt.
