From the frequently asked questions at the end of the 2005-2006 Texas Concealed Handgun law booklet:

Q: Where can I not take my handgun?
A: Handguns and other weapons cannot be carried at schools or on
school buses, at polling places, in courts and court offices, at racetracks,
at secured airport areas or within 1,000 feet of the premises of
an execution on the day of execution. The law also specifically
prohibits handguns from businesses where alcohol is sold if more than
half of their revenue is from the sale of alcohol for on-premises
consumption, and from locations where high school, college or professional
sporting events are taking place. You may not carry handguns in
hospitals or nursing homes, amusement parks, places of worship or at
government meetings
if signs are posted prohibiting them. Businesses
also may post signs prohibiting handguns on their premises based on
criminal trespass laws. See
Texas Penal Code § 46.035.
