Groveton, Texas (55 miles SW of Nacogdoches, 127 miles N of Houston), is the Trinity County Seat. According to TexasEscapes.com:
The Trinity County and Sabine Pass Land and Railway Company is credited with Groveton’s birth in 1881. The company built a mill and platted a townsite named Grovetown after a stand of trees. Residents preferred the name without the w and the current spelling came into being.
There's not much left of old Groveton (perhaps there was nothing to begin with).
Based on its numerous ghost signs, this old building may have once been a general store and/or service station. Today it houses an antiques store:
The owner of the antique store came out as I was taking pictures of and generally drooling over the neon sign. She told me it is from the 1940s and still lights up. Unfortunately, the wiring begins to smoke after it's been turned on for a while. And it's for sale - $5,000.
