The Brigade Chapel was designed by
Ernest Flagg. The cornerstone was laid in 1904 by
Admiral George Dewey and the dedication of the Chapel was on May 28, 1908. In 1940, the Chapel underwent remodeling which doubled the seating capacity to 2,500, to accommodate a larger brigade of midshipmen. From 1853 to 1972, chapel attendance was compulsory. After remodeling, the chapel formed a large cross. The dome over the chapel is copper and the
cupola is above the main altar area. In 1995, the Chapel was featured on a
U.S. Postal Service postage stamp, honoring the Academy's 150th anniversary. In 2009, nearly seventy years after the 1940 renovation and expansion, the chapel underwent an extensive restoration that included the repair of decades-long deterioration. The restoration uncovered the dome's -diameter
oculus (round
skylight), situated above the chapel floor, which had been plastered over for decades because of its deteriorating condition. The cost of the project was nearly $2.5 million, of which $925,000 was donated by the Class of 1969 to cover the cost of replacing the hardwood floors and refinishing the
pews. The remaining $2.3 million came from the government. ==Architectural features==
