[2] The two-block district is focused on what remains of Rockville's old commercial, governmental, and residential center, most of which was demolished during urban renewal in the 1960s.

The district includes the Romanesque Revival-style Red Brick Courthouse, designed by prominent Baltimore architect Frank E. Davis and built in 1891.

Located at 29 Courthouse Square, it houses the refurbished Grand Courtroom of Montgomery County Circuit Court.

The district also includes the 1931 Neoclassical-style Grey Courthouse and its 1960s addition; the 1939 Georgian-styled post office of limestone construction; and the 1930 Art Deco stone building built for the Farmers Banking and Trust Company.

The courthouses are part of a cluster of municipal and county buildings at the corner of Maryland Avenue and Jefferson Street (Rte 28) in downtown Rockville.
