The date was a few weeks earlier than some folks expected. The Worker Adjustment and Retraining Notification filed with the New York State Department of Labor in February stated that the store would permanently shutter on May 12. (H/T Bayou for that tip earlier this year.) Village Preservation reported that a 12-story building is possible.
Efforts to landmark No. 64-66 were not successful: Demolition permits were issued for this four-story building back in February, per the DOB. (The tenant on the upper floors, the Institute of Audio Research, closed in 2017.)
Agata & Valentina, which opened here in 2012, will continue on from their original (1993) Upper East Side location.
