Geography

Cityscape

The architecture of central Clayton reflects its economic activity and eras of growth. An impressive collection of mid-century modern low and high rise structures contrast with earlier mansions, stores and flats. Its surrounding residential neighborhoods maintain a dense, walkable character and were largely developed in the prewar era. These neighborhoods consist of brick walkups, apartment buildings, mansions and modest single family homes centered around several small business districts.

Neighborhoods

Claverach Park is a residential neighborhood bounded by Wydown Boulevard on the north, Ridgemoor Drive and Big Bend Boulevard on the east, Clayton Road on the south, and Audubon Drive on the west. The neighborhood was planned in the early 1920s by Julius Pitzman who avoided a traditional street grid in favor of curvilinear streets lined by stately trees, one centrally located neighborhood park, and 9 pocket parks. Oak Knoll Park, Clayton’s second largest park and the former home to the St. Louis Academy of Science, is located in the neighborhood.

Clayshire is a suburban neighborhood bounded by Forest Park Parkway on the north, Interstate 170 on the east, Clayton Road on the south and the Ladue city limit to the west and includes the subdivision of Tanglewood. Unlike Clayton’s denser prewar residential neighborhoods, Clayshire is characterized by a more postwar suburban development pattern. Neighborhood parks include Anderson Park, Clayshire Park, and Whitburn Park as well as a pedestrian underpass beneath I-170 that connects to Shaw Park. There is a small commercial area at the intersection of Clayton Road and Brentwood Boulevard.
