Rosemont is a neighborhood and census-designated place in Pennsylvania, on the Philadelphia Main Line. Partly in Lower Merion Township in Montgomery County and partly in Radnor Township in Delaware County, it is best known as the home of Rosemont College. It is the location of the 1894 gothic-revival Anglo-Catholic Church of the Good Shepherd. Rosemont is served by its own stops on both the Paoli/Thorndale Line of SEPTA Regional Rail and the Norristown High Speed Line.
