St. Nicholas Greek Orthodox Church and National Shrine is a Greek Orthodox parish and national shrine at the World Trade Center site in Lower Manhattan, rebuilt after the original church was destroyed in the September 11, 2001 attacks. Designed by architect Santiago Calatrava, the new church was consecrated in 2022 and serves as a place of worship and a shrine honoring victims of 9/11. It operates under the Greek Orthodox Archdiocese of America.
