Lincoln Square Gets $20 Million From Anonymous Donor To Complete New Building

Lincoln Square Synagogue announced Thursday night that an anonymous donor has committed to donating $20 million, which will be used to complete construction of the synagogue’s 50,000-square-foot building on the Upper West Side. The announcement was made at a special membership meeting “to share good news.”

The gift, however, comes with a string: It is contingent on the synagogue raising an additional $3 million by April 30, 2011. The synagogue’s leadership plans to launch an aggressive fundraising effort aimed at getting 100 percent participation from its membership.
