Mountainaire Hotel Historic District, Art Moderne hotel district in Hot Springs, Arkansas.

The Mountainaire Hotel Historic District consists of two nearly identical four-story masonry buildings at 1100 Park Avenue, clad in buff brick veneer with stepped Art Moderne facades. Built about 1947, they were part of a planned five-building complex and are among the few Art Moderne structures in Hot Springs.

A developer from Minnesota constructed these buildings in 1947 to create a hotel complex at this location. After about two decades serving as lodging, they were later converted to serve different purposes.

The buildings display a design style that is uncommon in Hot Springs and reflects the architectural tastes of the mid-twentieth century. Visitors can see the modern approach directly in the stepped facades and smooth brick surfaces that make the structures stand out.

The site is compact and easy to reach while walking along Park Avenue in Hot Springs. The facades are visible from the street, making it possible to see the buildings without needing interior access.

The project was originally envisioned as a larger complex that was never fully realized. Only two of the five planned buildings were constructed at this location, making it an incomplete testament to its era.
