Central National Bank (Apex Building)

The Apex Building is located at 633 Pennsylvania Avenue, NW at the intersection of Pennsylvania Avenue and 7th and C Streets.

This distinctive twin-turreted bank, is one of a cluster of financial buildings that distinguish Market Square as a prime 19th century business center. It is among the last 19th-century structures along the Pennsylvania Avenue ceremonial route.

Designed by prominent architect Alfred B. Mullett, it was built 1859-1960 as Seat on House, a Renaissance Revival-style hotel (renamed the Saint Marc in 1871). The building was purchased and extensively remodeled in 1887 by Central National Bank (including new facades, towers, banking hall, and iron vaults).

Its five stories showcase brown Seneca sandstone facades, a rock-faced granite base, and conical turrets with dormers and iron finials. The design echoes the old Center Market and illustrates the undulating projections permitted by building code revisions of the 1870s.

The structure was renovated 1984-1985. An addition was added during this renovation.
