Carnegie is full of impressive churches in a wide variety of styles. This one is in a heavy Romanesque style, and the bell tower (now festooned with loudspeakers) is appropriately impressive and weighty.
Addendum: The architect was James N. Campbell; the building was probably put up in about 1893. Source: Philadelphia Real Estate Record and Builders’ Guide, September 7, 1892: “J. N. Campbell has prepared the plans for a new Methodist Church to be erected at Mansfield, Pa., at a cost of about $30,000. The pastor is Rev. G. T. Reynolds.” (Carnegie was formed from the two boroughs of Mansfield and Chartiers.)
