Synagogue of Arlon, Romanesque Revival synagogue in Arlon, Belgium

The Synagogue of Arlon stands on Rue de la Synagogue, its street facade of grey stone and tan stucco capped by a steep gable roof. Two slender octagonal spires of alternating red and pale stone bands rise at the outer corners. A large round window sits in a recessed arch above the dark double door, reached by a short flight of stone steps; two small arched windows open high under the gable, and carved rosettes and diamond ornaments cover the wall. The provincial architect Albert Jamot designed it, and the interior decoration was finished in 1872.

Built in 1865, this was the first synagogue structure constructed in Belgium, with public funds covering most of the building costs. During World War II, the building was repurposed, but its interior contents were protected through careful measures during that difficult period.

The exterior displays Jewish symbols including the Tables of the Law in the triangular pediment and decorative elements in the twin bays. These details reflect the building's role as a religious and cultural gathering place for the Jewish community.

The building underwent major restoration work from 2014 to 2019 to address moisture damage and dry rot that had weakened the structure. After these repairs were completed, it reopened and became accessible to visitors again.

The 2014 closure was caused by damp and dry rot that threatened the building's stability. The restoration, estimated at about 400,000 euros in 2016, was funded sixty percent by the Walloon Region and the rest by the city of Arlon. In 2015 the Association des musulmans d'Arlon collected 2,405 euros for the work.
