The Hechal Yehuda Synagogue, also commonly known as the Recanati synagogue, is one of approximately 500 synagogues in the second largest city of Israel, Tel Aviv. Situated on the Menahem ben Saruq street in the city's centre, it is often referred to as the Seashell Synagogue because of its unusual shape resembling a seashell. The design is inspired by the seashells on the shores of the Greek city of Thessaloniki, which is the hometown of the wealthy Recanati family. It was the Recanati family who donated the money for the synagogue. It is affiliated with Orthodox Judaism.
