Rockville’s “Old” Post Office

In 1794, federal mail service began in Rockville, known then as Montgomery Court House.  Stage coaches carried the mail along the post road between George Town and Frederick (today’s route 355), part of the new nation’s system of communications and post roads.  Local postmasters were selected for their political affiliations, and for most of Rockville’s history our post office could be found in the corner of a store on the main street.

By the mid-1930s, Rockville’s population was about 1,500, County government had erected the Grey Courthouse, and across the street arose a stately bank in the Art Deco style.  It was time for Rockville to have a permanent post office.

The Federal Government paid $35,000 for the lot on the corner of Montgomery and Washington Streets, then demolished the small frame buildings that had housed the Sentinel newspaper since 1855.  Construction began in November 1938 and cost $42,000. Rockville celebrated the dedication of the Post Office on July 22, 1939.  Following a parade watched by 3,000 people, a bevy of speeches, and a reception for special guests at Glenview farm.

Rockville’s post office was one of 406 constructed under the Public Works Administration (PWA).  Despite the desire to complete projects rapidly, PWA stressed the importance of high quality to ensure “public works of an enduring character and lasting benefit.”

Architecturally, the English Georgian style post office blends modern and classical elements. Smaller than similar buildings erected in Bethesda and Silver Spring around the same time, perhaps it reflects projections for Rockville’s future growth.  One story high with a corner hexagonal entrance tower, the brick and limestone building anchors a prominent corner.


The interior of Rockville’s Post Office is beautiful as well as functional.  Fifteen foot ceilings look down on terrazzo floors and walls, the original bulletin boards and postal boxes, bronze grilles, and a handsome mural.  Most striking is the mural of Sugarloaf Mountain by Judson Smith, which was sponsored by the Treasury Department’s Fine Arts Section with funds based on one percent of the total construction cost. In the 1990s, the original brass and glass boxes were on the way out, but fortunately the postmaster lent a sympathetic ear to long-time users and preservationists and retained them in the lobby.

Many a Rockville youth reported to the draft board in the tower room above the post office. U.S. military recruiters moved into the administrative offices after a new main post office facility opened at 500 North Washington Street in 1965. By that time, new stations had opened in Twinbrook and on Rollins Avenue. The General Services Administration (GSA) took title to the property in 1949.

The old Post Office was designated as a Rockville Historic District in 1979 and listed in the National Register of Historic Places in 1986.  In addition to being a charming vestige of Rockville’s old main streetscape lost to urban renewal redevelopment, the 1939 post office was well used for 67 years and beloved by its many patrons in Town Center.  It closed for post office business at 4:30 pm on October 27, 2006, and immediately moved into GSA’s surplusing process.

In 2008, GSA transferred the property to the City at no charge with the condition that it would be used for homeland security and public safety purposes.  Three years later, the renovation of the historic building and construction of a new annex for use as the police headquarters for the City began and was completed in 2012.  On October 20, the Mayor and Council of Rockville dedicated the new police station and Rockville’s “old” Post Office starts a new life.
