 To design the new structure, the congregation chose Frederick C. Sauer, designer of the Allegheny St. Nicholas.Construction began in 1900 and completed in 1904.Because the St. Nicholas in Allegheny burned in 1921 and was replaced by a new church in 1922, again designed by Sauer, the Troy Hill St. Nicholas was an older structure leading many to believe it was the first of the two congregations.
