The European Heritage Training Course is the continuation of courses and projects following the theme of Jewish heritage in Halberstadt which had taken place in 2018, 2019, 2020 and 2021. This engagement has been an important collaboration between European Heritage Volunteers and the Moses Mendelssohn Academy both to raise awareness about the importance of Jewish heritage in Halberstadt as well as to promote its documentation and conservation for posterity. In this sense, the training course will be focusing on the protection of the remaining ruins of the Baroque synagogue which was destroyed in 1938/39, a task which had already begun with the training course that took place in 2021. During that previous European Heritage Training Course, the structures and damages of the remains of the former synagogue had been documented, thus laying the groundwork for the interventions that will take place in 2022. The 2022 training course will focus on conservation and restoration interventions on the remaining wall of the former entrance hall. The participants will learn the complete process from the preparation of mortars, the manufacturing of the stone supplementary compounds and colour matching with pigments to the adjacent stone surfaces, up to mixing the glazes for retouching the various stone surfaces. Afterwards, they will develop a concept for securing the fragments of paintings on the walls and producing a sample pattern axis. As a second activity, the participants will clear and clean the mikveh at Bakenstrasse 56. The work will require pumping out the basin to expose the bottom, and passing the mud through a sieve to ensure a thorough inspection of the residues for any potential finding of historical interest. Once the mikveh is cleared of debris, it will set it for a more wholesome interpretation of the mikveh as a historical relic from the Jewish life in Halberstadt. In addition, during an earlier training course pieces of original plaster at a historic wall located in the garden of the former synagogue have been conserved. The participants of the 2022 training course will be tasked with continuing preventive protection measures by backfilling and filling the worn-out plaster pieces, and applying lime mortar to protect the flanks of the fragments, with the effect of stabilising them. Finally, a research of the original colours in the passage in Bernd Lehmann Museum at Judenstrasse 26 will be undertaken to identify possible paint and colour layers present there. The work will be coordinated by a certified restorer with a specialisation in the restoration of plaster, stucco and wall paintings. In the frame of the educational part, various lectures and guided tours as well as an excursion will be organised so that the participants can gain comprehensive and detailed knowledge about the Jewish history and heritage in Germany and Europe. The visits will also contextualise the training course by providing an overview of the rich history and the high valuable heritage of Halberstadt in general.

Accommodatie en maaltijden

FINANCES All costs linked to the project are covered, including food, accommodation, insurance and transportation during the stay at the project. Travel costs to and from the camp place are not covered. Participants should organise their journey to and from the project place by themselves and on their own expenses. Furthermore, participants should bring their own pocket money. ACCOMMODATION In most of Open Houses' camps the volunteers will live at the same places they also work on, what means that they live more or less on a building site. In most of the Heritage Volunteers Projects the accommodation is located in a certain distance to the working site. The accommodation is usually very simple; there are shared rooms with simple beds or mattresses at most of the places. Shower, toilet and kitchen are at the place, but sometimes not in the same building. The equipment is simple but fair. After work, when everybody wants to take a shower, there can be a limit of hot water. FOOD The meals will be prepared together as they are part of the community life, what means that every participant will be responsible for the meal at least once during its stay. So it would be very nice if the participants could bring typical recipes from home in order to introduce each other to the preparation of food from all over the world.

Locatie en vrije tijd

Situated at the foot of the Harz Mountains, Halberstadt is a town adorned by beautiful religious architecture and traditional timber constructions. It is also well known as being the seat of a historical Jewish community which became the epicentre for the development of Jewish Neo-Orthodoxy. These ideas enabled the preservation of Jewish laws and customs within communities that at the same time were keen to embrace modernity, secular society and the modern world. Since at least the 13th century, a Jewish community has existed in Halberstadt. Around the year 1700 the famous royal resident of Poland and agent of the Saxon court, Berend Lehmann (1661 – 1730), established here a house of learning, the so called Klaussynagogue. The community grew in importance attracting learned scholars and those interested in learning from them. The Jewish community in Halberstadt became characterised by eruditeness and developed from the middle of the 19th century on into one of the centres of the Jewish Neo-Orthodoxy. Distinguished rabbis such as Eger, Auerbach, Hildesheimer and Hirsch are intrinsically connected with Halberstadt’s history, and transformed it into one of the most important Jewish communities in Middle Germany. In 1712, a splendid Baroque synagogue, built by the Court Jew Berend Lehmann, was inaugurated. Hidden from view behind the buildings of the Bakenstrasse and Judenstrasse, the cupola of the synagogue surmounted the height of those buildings twice. The synagogue building was the first one in Germany built following a defined architectural concept. At the end of the 19th century, the entrepreneurial Hirsch family decided to invest in the modernisation of the building, extending it by erecting an entrance hall. During the “Night of Broken Glass” – the Progrom Night – on November, 9th, 1938, the synagogue was plundered, and all Tora scrolls were burnt in the street. On November, 18th the building inspection ordered the demolition of the synagogue, which was initiated the next day. The Jewish community of Halberstadt had to bear its costs. The remaining wall which still stands is the outer wall of the former entrance hall. Of the rest of the structure, only the foundations and the flouring have remained. Not a single object from the splendid interior is preserved. The building complex enshrining the ruins also houses the Moses Mendelssohn Academy with the Berend Lehman Museum. In the vicinity, it can also be found the Klaussynagogue which was established around 1700. Following its traditional purpose, the house became in 1998 again a seat of study and science, a place of encounter and exchange for Judaic knowledge. The synagogue, enclosed by the houses of the Bakenstrasse and Judenstrasse, is now a place of remembrance, where a contemporary art installation stands as a reminder of the destroyed place of prayer. The main entrance to the remains of the former synagogue leads through the gateway of the Jewish community’s former cantor’s house in Bakenstrasse 56, where a traditional mikveh has been uncovered on its basement. During renovation works on the house, the mikveh, which had previously been filled with rubble and coal, was discovered unexpectedly. Translated from the Hebrew, mikveh means "accumulation of water". A mikveh, or Jewish ritual bath, is a basin with accumulated water which cannot be filled artificially, but rather has to be filled by a natural flow or by ground water since the Torah says it does not have cleansing properties otherwise. It was used to purify people or religious objects through a ritual bath before partaking in religious activities such as the Sabbath, before important festivities or to prepare people before or after yearly cycles. Nowadays, mikvehs are rarely used by men. It is now mostly a ritual reserved for women in Jewish Orthodoxy, who are required to use a mikveh before their wedding, for the birth of a child and after every menstruation.
