History
Bandelier National Monument preserves more than 33,000 acres of the Pajarito Plateau in north-central New Mexico, protecting one of the densest concentrations of Ancestral Puebloan architecture in the American Southwest. The principal occupation of Frijoles Canyon spans roughly AD 1150 to 1600, with tree-ring dating placing the main pueblo's construction between 1383 and 1466. Sites within the monument document the Pueblo III and Pueblo IV eras, when ancestors of the present-day Cochiti, San Ildefonso, Santa Clara, and other Rio Grande Pueblo communities consolidated into the canyon's sheltered floor and along its south-facing cliff walls.
The builders employed two distinct construction traditions, both rooted in locally available volcanic material. Along the canyon walls they carved cavates — small, hand-hewn chambers — directly into the soft pinkish-white tuff deposited by the Valles Caldera eruptions more than a million years earlier. The same tuff, when broken into manageable blocks, was laid up as masonry to build talus houses against the cliff base and free-standing pueblos on the canyon floor. Walls were typically chinked with smaller stones and finished with adobe mud plaster, while floors, hearths, and roof systems were sealed with the same earthen mixture. This combination of carved rock and adobe-finished masonry represents a distinctly Puebloan vernacular adaptation to the geology of the Pajarito Plateau.
The centerpiece site is Tyuonyi, a single-entry circular pueblo of roughly 400 rooms that once rose one to three stories around a central plaza containing three kivas. Adjacent features include the Long House, a continuous run of multi-story talus dwellings stretching nearly 800 feet along the cliff, and Alcove House, a ceremonial space reached by ladders some 140 feet above the canyon floor. Petroglyphs and pictographs are preserved throughout the complex.
The monument was established by presidential proclamation on February 11, 1916, by Woodrow Wilson and named for Swiss-American anthropologist Adolph F. A. Bandelier, who documented the sites in the 1880s. It was added to the National Register of Historic Places in 1966. A Civilian Conservation Corps historic district at the visitor center, built of native stone and timber between 1933 and 1941, was later designated a National Historic Landmark. The site is administered by the National Park Service.
