The cause of the fire becomes clear.
No one was inside at the time of the 3-alarm fire, which reportedly destroyed the interior of the synagogue.
The FDNY is continuing to search the site for any possible victims, although no missing persons have been reported.
Three people were seen on a surveillance video running from the building, which had been abandoned for a decade, according to reports. It is known that people have been coming and going from the building.
"They don't make buildings like this anymore, and it's not just the physical beauty, but the prayers that were sung many years ago".
The building closed in 2007 because membership had dwindled, the rabbi said.
But Rabbi Mendl Greenbaum of Beth Hamedrash Hagadol told the Lo-Down that he was due to meet with the LPC soon about restoration plans for the building. "For us, besides a community tragedy, it's a personal family tragedy as well".
It took 138 fire fighters and 33 emergency vehicles from three different fire stations to get the fire under control Sunday and two fire fighters received minor injuries as a result, according to an FDNY spokesman.
The cause of the fire is still under investigation, an FDNY spokesman said Monday.
Some advocated for the empty structure to be torn down while other groups, including one on Facebook, wanted to save it with some pushing for a major multi-million dollar fundraising campaign to restore the building in need of fix.
