The area around the South Battery, south of the Parade Ground, includes several former service structures. Building 301, a single-story brick building near the waterfront, housed an elementary school called PS 26. It was originally built in 1934, though two wings were added in 1959–1960. To the west is building 324, constructed in 1926 as the Army YMCA. The War Department Theater (building 330), a two-story 700-seat theater built in 1937–1939, is located west of the YMCA, facing the southern portion of Governors Island.
