The U-Drop Inn, also known as Tower Station and U-Drop Inn and Tower Café, was built in 1936 in Shamrock, Texas along the historic Route 66 highway. Inspired by the image of a nail stuck in soil, the building was designed by J. C. Berry. An unusual example of art deco architecture applied to a gas station and restaurant, the building features two flared towers with geometric detailing, curvilinear massing, glazed ceramic tile walls, and neon light accents. It has traditionally held two separate business: "Tower Station," a gas station on the western side, and the "U-Drop Inn," a café on the eastern side. Though it has passed hands several times in its history, the building has consistently housed the same types of businesses it was originally constructed for.
Once considered a beautiful and impressive example of Route 66 architecture in Texas, the U-Drop Inn fell into disrepair with the decommissioning of Route 66. It closed for business in the late 1990s. After it was listed on the National Register of Historic Places in September 1997, the building was purchased by the First National Bank of Shamrock, which then gave it to the city.
