The Upper and Lower Pontalba Buildings, which make up the 1850 House, were built by the Baroness Micaela Almonester de Pontalba, the daughter of Don Andres Almonester y Roxas, the Spanish colonial landowner associated with the neighboring Cabildo, Cathedral, and Presbytere. Inspired by the imposing Parisian architecture the Baroness favored, the rowhouses were intended to serve as both elegant residences and fine retail establishments.

To illustrate the landmark's historical significance, the State Museum has recreated what one of the residences would have looked like during the Antebellum era when the Baroness Pontalba first opened her doors. Furnished with domestic goods, decorative arts, and art of the period, the 1850 House depicts middle-class family life during the most prosperous period in New Orleans's history. Limited docent- and curator-led tours are available, as is self-directed viewing.

The Museum exhibits over 120 cars ranging from 1894 to 1999 and automotive displays on three floors. The museum has the most extensive collection of Auburn, Cord, and Duesenberg automobiles in the world, and features the largest exhibit of Duesenberg automobiles on public display in the world.

The museum offers exhibits, tours, research library access, educational programs, and recreational and educational events.

D.O. Tripp and Mathias Parkhurst built the Woodside Store in 1854. Early customers included loggers chopping down the redwoods. Dr. Tripp sold them everything from work boots and ax handles to flour and ham. When farmers settled in the area, the Woodside Store served as their county store, post office, and community center until 1909. Today, visitors can browse the shelves of the Woodside Store, restored to its 1880s appearance, and see the goods available in the mid-to-late 1800s—from canned fruit and frying pans to nails and sewing machines.

The store offers exhibits, educational programs, and occasional recreational and educational events (including living history events).

Mission Mill Museum interprets the history of the Thomas Kay Woolen Mill which produced wool products from 1889 to 1962 and represents one of Oregon's earliest and strongest industries. Mission Mill also interprets the history of Jason Lee's Methodist Mission to Oregon which settled in the Willamette Valley in 1834 before the major Oregon Trail migrations. The missionaries brought formal education, industry, and large scale agriculture and advocated for U.S. government in the Oregon country. The Museum preserves Mission houses; an Oregon Trail settler's house; a historic church; and the structures, equipment, and original water-powered turbine of the Thomas Kay Woolen Mill with related artifacts. The museum's two histories are shared with visitors through individual and group tours, interpretation, speakers, living history, children's programs, hands-on activities, and special events.

In 1906, John Huddleston, the local farmer who owned this property, found the first diamonds here in Murfreesboro, AR, and started the diamond mining rush. After a series of ill-fated mining ventures followed by tourist attractions, the site became an Arkansas state park in 1972. Visitors today are invited to prospect in the park's diamond search area, a 37-acre plowed field that is the eroded surface of an ancient volcanic pipe that, 95 million years ago, brought to the surface the diamonds and some of the semiprecious stones lucky visitors find here today. Within the park boundary many remnants of old mining ventures remain including the Mine Shaft Building, the Guard House, mining plant foundations, old mining equipment, and smaller artifacts. Nowhere else is North American diamond mining history as evident or as well-preserved as here.

The site offers short films, exhibits, tours, educational programs, and occasional recreational and educational events.
