The world headquarters and mother church of the Christian Science faith mixes the traditional with the modern—marrying Bernini to Le Corbusier by combining an old-world basilica with a sleek office complex designed by I. M. Pei & Partners and Araldo Cossutta, Associated Architects. Mary Baker Eddy's original granite First Church of Christ, Scientist (1894) has since been enveloped by a domed Renaissance Revival basilica, added to the site in 1906, and both church buildings are now surrounded by the offices of the Christian Science Publishing Society, where the Christian Science Monitor is produced, and by Cossutta's complex of church-administration structures completed in 1973. You can hear all 13,000-plus pipes of the church's famed Aeolian-Skinner organ during Sunday services.
The outer reflection pool, small fountains, and surrounding area (together with the church and the Mary Baker Eddy Library, the area is known as the Christian Science Plaza) received a major face-lift recently to include more walkways and sitting areas. Church tours are held Friday and Saturday at 11 am, 1 pm, and 3 pm, and on Sunday at 1 pm and 3 pm.
