Here is Thorncrown Chapel just outside of Eureka Springs. It looks open air but actually is made with over 6,000 square feet of glass in its 425 windows. It has won several architectural awards, including being placed 4th on the American Institute of Architects' list of the top buildings of the 20th century.
Here is a view from inside:
Here is the very first Walton's 5-and-Dime store, on the square in Bentonville, Arkansas, which of course grew to become the world's largest retailer, Wal-Mart. Today this store is the Visitor's Center and Museum.
Here is a recreation of Sam Walton's first desk in the Museum. Pretty humble beginnings for someone who ultimately became (for a while) America's richest man.
Here is a view from the parlor in "Miss Laura's Social Club," a former bordello which is now the Welcome Center in Fort Smith, Arkansas. It is on the National Register of Historic Places, the first such establishment to be so honored. Note the red lamp.

The dining car of the MKT (Missouri - Kansas - Texas) railroad, on display outside the Fort Smith Trolley Museum.
The trolley lines disappear into the desolate part of Fort Smith. On the left is part of a mural that has been painted on the old trolley depot.
In the 1800's the boundary between the US and Indian Territory was on the Arkansas side of the Arkansas River, as painted on the sidewalk outside the Fort Smith National Historic Park, as night was falling.
