Waggoner Mansion
Also known as: El Castille
Why it's listed
Built in 1883 at 1003 E. Main in Decatur, this sixteen-room limestone mansion, also known as El Castille, was the home and ranch headquarters of cattleman Daniel Waggoner. Waggoner drove Longhorns into Wise County in the mid-nineteenth century and was recognized as a cattle king by 1870. By 1900 the Waggoner Ranch covered over a million acres and supported more than 60,000 cattle. After oil was found on the ranch in 1903, the family fortune grew further. The house retains about ninety percent of its original material, including 18-foot ceilings downstairs, carved door mouldings with a Lone Star motif, stained glass transoms, eight tiled fireplaces and frescoed ceilings. William Thomas Waggoner restored it in 1931. Outbuildings include a smokehouse, storm cellar and an original ranch bunkhouse. The exterior was duplicated as a set for the film Giant. The mansion is valued as a striking remnant of Texas's Victorian cattle empire.
Significance in brief: The nomination argues the house is an excellent, highly authentic example of Texas Victorian masonry architecture, retaining about ninety percent of its original craftsmanship and material. It was also the headquarters of the Waggoner Ranch and home to a family that became one of the richest and most influential in the Southwest through cattle and oil.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
