The U.S. Post Office and Courthouse is a historic government building located in Laredo in Webb County, Texas.

Laredo's allegiance remained with Mexico until 1845, when the United States annexed Texas and the Mexican–American War subsequently began.

[2] During the late-19th century, Laredo entered a period of economic prosperity stimulated by the railroad, coal mining, and irrigated farming.

As Laredo became known as the gateway to Mexico, the federal government began preparations to construct a new post office, courthouse, and custom house.

In 1935, the Office of the Supervising Architect of the Treasury, then overseen by Louis A. Simon, designed an addition to the building to accommodate the growing space needs.

[1] The U.S. Post Office and Courthouse, a significant local landmark in Laredo, is an excellent example of the Neoclassical style of architecture.

Each carving includes an articulated keystone beneath an oval medallion crowned with a shell motif called a coquillage.

At the eastern and western ends of the facade, glazed, multi-pane doors on the second story have segmental arched openings with articulated surrounds and keystones.

[2] The projecting central portion of the upper stories contains a classical portico with a pediment supported by four, two-story Roman Doric order columns.

The tympanum, or triangular area of the pediment, contains a single, large, centrally placed patera that is flanked with a foliated pattern.

The second-story courtroom was previously partitioned for office space, but converted back to a single room in 1972, although neither the furniture nor the finishes were restored.
