Our Lady of Leliendaal Church was originally owned by the Norbertine St. Michael's Abbey in Antwerp. The architect was Lucas Faydherbe, he came from Mechelen, was the nephew of Lucas Franchoys the Younger and studied with Peter Paul Rubens in Antwerp. In 1662, the foundation stone was laid. Construction was delayed on multiple occasions, because the façade tilted dangerously forward. Therefore, in 1664, the façade was demolished and rebuilt. In 1670, the first Mass was said and in 1674 it was solemnly inaugurated.
In the early 19th century, during the Napoleanic wars, the church was seriously neglected and half of it was turned into a hospice for the poor of the city. The furnishings were sold and holes were made in the gables for people to be able to see out and over the church to help defend it against attack. A wall was placed in the church between the second and third windows for the establishment of an infirmary.
In 1834, it re-opened under the administration of the Jesuits. Through the cooperation of the nearby Minor Seminary and the Civil Hospices, it was restored and equipped with new furniture and the internal walls were removed. In 1900-1901, the Jesuits changed the floor plan and moved the choir to the gallery in the west of the church. Later in the 20th-century, a sacristy was constructed in the south west part of the church. Also, a grotto to Our Lady of Lourdes was built and new furniture was purchased.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.
