General Plan for the Improvement of the U.S. Capitol Grounds
by Frederick Law Olmstead, 1874
Following the extension of the Capitol in the 1850s-1860s, the grounds were enlarged in 1872. In 1874 Congress commissioned Frederick Law Olmstead to design landscape improvements, and he soon produced this drawing, which guided the project over the next two decades. He described the plan as "very simple, with the purpose of its perfect subordination in interest to the architectural design of the Capitol." Olmsted's objective was to provide a dignified "park-like" setting for the Capitol, with groupings of trees and expansive vistas designed to set the Capitol square apart, as an oasis, from the surrounding, developing city. Today the grounds have evolved into an arboretum with hundreds of mature botanical specimens--many of which are rarely seen elsewhere.
1. First Street Boundary Wall, Fountain, and Lanterns
Olmsted did not include boundary walls along the perimeter of the Grounds in his original 1874 landscape design. However, in an effort to separate the Capitol's tranquil setting from the bustling city, Olmsted incorporated multicolored stone walls and piers in the construction to define the edge and entrances to the grounds. Piers of pink granite topped with bronze lanterns
Constructed in 1879-1880, the Summerhouse offered visitors a shaded place to rest, admire views of the Capitol, and have a drink of water. Olmsted's principal architectural assistant, Thomas Wisedell, was the designer. The Summerhouse is a tribute to the bricklayer's craft--constructed of carved and radial brick, creating elaborate architectural features. Nestled in the hillside, the structure features a "grotto" with running water that, along with the central fountains, add a cooling effect during the summer.
3. The Olmsted Terrace
Constructed in 1884-1982 on the north, west, and south sides of the Capitol, the marble terrace provided a strong visual platform, correcting the illusion that the massive building was about to slide down Capitol Hill. It also added much-needed space for storage, shops, and committee rooms.
