The detailed architect of the Kaltinėnai Synagogue is not explicitly mentioned in accessible records. Furthermore, there is no specific information about the primary architect behind its construction.

As for its later use, the Kaltinėnai Synagogue was repurposed from its original function. Today, it no longer serves as a synagogue but has been transformed into a home for the elderly and a rehabilitation centre (source).

If you require more specific information or historical details regarding the architect, contacting local historical archives or Jewish heritage organizations in Lithuania may provide more precise insights.
