The main sanctuary is used only on the Sabbath and holidays, while weekday services take place in the underlying smaller rooms of the complex. Under the main sanctuary are multiple floors. The floor directly under the main sanctuary hosts a large number of small synagogue rooms known as shtieblach where services for shacharis, mincha and maariv are held up to every 10 minutes. In an adjacent wing is also a large hall used for tishen. Below the shtieblach are multiple floors with dormitory-style sleeping quarters for Belzer Chassidim from outside of Israel, who come to visit the Rebbe for Jewish holidays such as Rosh HaShana, Yom Kippur or Sukkos. There are also large rooms for other functions, such as seudas shlishis on Shabbos afternoons, weddings and bar mitzvah celebrations.
