The Rebbe’s shul in 770 was entirely emptied and cleaned for Pesach.
If you go to 770 these days to find a minyan or learn you might be surprised to find that things aren’t business as usual there. The Rebbe’s shul in 770 is being cleaned for Pesach. From this morning up until Yomtov the shul is off-limits, with only small parts of the downstairs available for minyonim.
