The nine windows on the top story of the Liberty Street building have been taken up by large signs. The first six windows use the symbols of world religions to spell out "coexist," starting with an Islamic star and crescent for the "C" and finishing with a Christian cross for the "T."
The other windows contain a biblical reference and other phrases. A representative for hip-hop mogul Simmons says it will be up until at least Sept. 11.
Supporters of the Islamic center say religious freedom should be protected. Opponents say it should be moved farther from ground zero.
