Each year, tens of thousands of ultra-Orthodox Jews travel to Uman, Ukraine to visit the grave of Rabbi Nachman of Breslav on Rosh Hashanah, the Jewish new year.
Located between Kiev and Odessa, the tomb of the 18th century founder of the Breslov Hasidic movement constitutes one of the holiest sites in the Hasidim world.
Ukraine-based photographer Arthur Bondar documented the celebrations in Uman in past years. "They go to the lake, praying, reading psalms and throwing stones in the water," Bondar says of the pilgrims.
Take a look at Bondar's incredibly photos in the slideshow below, and find more of his work on his website.
