Types of Texas Historical Markers

The THC has three different application forms for markers which are the RTHL – Recorded Texas Historic Landmarks. HTC – Historic Texas Cemetary marker and the Subject marker. Click read more to see detail information about the types of Texas markers.


Recorded Texas Historic Landmarks (RTHL)
are properties judged to be historically and architecturally significant. The THC awards RTHL designationto buildings at least 50 years old that are judged worthy of preservation for their architectural and historical associations. RTHL is a legal designation and comes with a measure of protection; it is the highest honor the state can bestow on a historic structure. Purchase and display of a historical marker is a required component of the RTHL designation

process. Owners of RTHL-designated structures must give the THC 60 days notice before any alterations are made to the exterior of the structure. Unsympathetic changes to these properties may result in removal of the designation and historical marker. To nominate a property, the owner’s consent is required.


Historic Texas Cemetery (HTC) markers
are only for burial grounds previously awarded a HTC designation. These markers recognize the historical significance of a cemetery and, with the use of interpretive plaques, provide background on associated communities, families, events, and customs. HTC markers must be placed at the cemetery, but since cemeteries are protected under other existing laws, they convey no restrictions on the property


Subject marker
are solely educational, and reveal aspects of local history that are important to a community or region. These markers honor topics such as church congregations, schools, communities, businesses, events, and individuals. A subject marker is placed at a site that has a historical association with the topic, but no restriction is placed on the use of the property or site. No legal designation is required for a subject marker.
