National Park Service Southwest Regional Office in Santa Fe, New Mexico

Published on March 27, 2026

The National Park Service Southwest Regional Office Building, now known as the Region III Headquarters Building, plays a crucial role in providing support services for Park Service properties throughout the intermountain region of the American Southwest. Conveniently located on the south side of Old Santa Fe Trail, at its junction with Camino del Montel Sol, the office resides just north of Santa Fe’s major museum district.

Constructed in the 1930s the Civilian Conservation Corps, with funding from the Works Progress Administration, this traditional adobe building exemplifies Spanish Pueblo Revival architecture. Designed in 1937 architect Cecil Doty, the building was designated a National Historic Landmark in 1987. With a sprawling footprint of 24,000 square feet, it stands as the largest known adobe office building in existence. The design mimics that of a traditional mission compound, featuring a central patio, adobe walls finished in cement stucco, and flagstone floors in the main lobby.

Entering the building transports visitors to a time reminiscent of Spanish mission architecture. The main area houses cabinets displaying local artifacts alongside paintings and plaques honoring significant figures from the region’s history. The central patio boasts a circular fountain, surrounded and plantings that evoke a sense of history. As one wanders through the courtyard, it’s easy to imagine brown-cloaked monks tending to their duties amid the serene atmosphere. The open space and Santa Fe skies converge to create a timeless environment, imbued with the distinct character of the area that is both difficult to describe and to replicate.
