Mason Texas is the County Seat of Mason County Texas and located just west of Llano Texas. My favorite fact about Mason Texas is that Old Yeller- the beloved book was written by Mason TX resident Fred Gipson and the movie Old Yeller premiered at Mason’s Odeon Theatre which is still in business today. Known as the “Gem of the Texas Hill Country”, Mason has a beautiful town square. You can stay in a historic Bed and Breakfast while looking at Historic Homes in Mason Texas.
