The Ohel Yitzchak Synagogue also known as the Shomrei ha-Chomos Synagogue and the Ungarin Shul (Hungarian synagogue) is located in the Muslim Quarter of the Old City of Jerusalem. It was built as a yeshiva in the 1870s by Kolel Shomrei HaChomos, an organization of Hungarian Jews, but was abandoned after the riots of 1938. Although the building was destroyed after 1948, it has recently been acquired by a Religious Zionist group for refurbishment and was reopened after restoration work finished in October 2008.
