St. Nicholas R.C. Croatian Church, North Side, located at 1326 E. Ohio Street in Pittsburgh, PA, U.S.A., is the first Croatian Parish in the Western Hemisphere. When the Pennsylvania Department of Transportation's plans to widen the East Ohio Street/Rt. 28 highway threatened St. Nicholas Church, the Preserve Croatian Heritage Foundation (PCHF) was formed in 2000 for the sole purpose of "saving and preserving" St. Nicholas Church.

For 12 years, members of Preserve Croatian Heritage Foundation (PCHF) have been working diligently to accomplish this mission even though there have been many obstacles to overcome. When St. Nicholas Church was abruptly closed in 2004 by Pittsburgh Diocesan officials with the understanding that St. Nicholas could no longer be a house of worship, PCHF pursued the direction of acquiring the St. Nicholas Church buildings and converting them into a National Immigrant Museum. The museum will be an honorable way to pay tribute to our Croatian ancestors, as well as other nationalities, for future generations.

In 2009, the Northside Leadership Conference (NSLC) joined in the efforts of PCHF, and their Executive Director is currently negotiating a sales agreement with the Pittsburgh Catholic Diocese's officials for the acquisition of St. Nicholas Church to be converted into a National Immigrant Museum. The sales agreement is contingent on the results of a Geological Technical Study on the hillside behind the Church to ensure it is stable. We are closer than ever to reaching this goal. We ask for your support and prayers for this plan to come to fruition.
