The estate was designed by Carrère & Hastings of New York and built by 1895 for industrialist John C. Pitcairn.","why_significant":"The nomination argues the estate is significant for its association with John C. Pitcairn, founder and president of Pittsburgh Plate Glass Company and a layman central to founding The Academy of the New Church and Bryn Athyn. It also argues the complex is an exceptional, well-preserved example of Beaux-Arts residential design with high integrity of its buildings, walls and gates.","narrative":"Set on a ridge near Pennypack Creek in Bryn Athyn, Pennsylvania, Cairnwood is a country estate of orange Roman brick and buff Indiana limestone, designed in 1892 by the New York firm Carrère & Hastings and largely complete by 1895. The main house has 28 rooms and a chapel in its third-story turret, with a slate roof, a stone balcony over the entrance loggia, and glass supplied by Pitcairn's own Pittsburgh Plate Glass Company. Its walled grounds include a garden house, a stable with five stalls, and a garage complex added in 1911 with a studio designed by Duhring, Okie & Ziegler. John C. Pitcairn lived here with his family from 1895 until his death in 1916. He had built a career in railroads and oil before founding the plate glass company, and he became the main benefactor of The Academy of the New Church and the funder of its cathedral. The estate is valued for its link to his industrial and religious work and for its architecture.","period_of_significance":"1895-1916","architect_builder":"Carrère, John (1858-1911) and Hastings, Thomas (1860-1929), architects; J.
