The Tower Conoco Service Station and U-Drop-Inn Restaurant building was finished in 1936 and its unique Art Deco-style brick and glazed green tile architecture, complete with twin towers, made it one of the most distinctive landmarks along the entire length of Route 66. After a period of gradual decline, the business finally closed for good in the 1990s. In 2003-04 the building underwent specialist restoration and - a little peeling paint aside - looks as smart and striking today as it ail have done at any other point in its long history.
If you go:
The building has been adapted into a museum, visitor center and gift shop, and is also home to the Chamber of Commerce.
