The Kossov Synagogue on Alkabetz Street is one of Tzfat’s most storied Chassidic shuls. Founded by immigrants from Kosov, Galicia (Poland) who arrived after the 1837 earthquake, it was built to continue the traditions of Rabbi Menachem Mendel Hager of Kosov. The community declined over the 20th century and the building fell into disrepair, but it was reopened and renovated by an English-speaking Chassidic community and today runs daily minyans. The Biala Rebbe, who maintains a home in Tzfat, prays here regularly. The outer wall bears a memorial to the Jews of Kosov murdered in the Holocaust.

A wooden plaque at the shul marks the founding of the holy community of Kosov in Tzfat in 5608 (1847). The shul was the home of Kollel Kosov, which collected Rabbi Meir Baal HaNes charity for the Kosov community in the Land of Israel. A dedication board records that the building was dedicated by Joseph Frohlich West, born and raised in Kosov and later of Melbourne, Australia, in memory of his wife, Helena Chaya.
