Landmarks are resources that have been officially recognized by the City of San Antonio for their outstanding historical, cultural, architectural, or archaeological significance. There are currently over 1,500 designated landmarks in the city. In the past, landmark designation identified Historic Exceptional (HE) and Historic Significant (HS) landmarks. 2010 amendments to the City's Unified Development Code (UDC) include the consolidation of the two landmark designations into one Historic Landmark (HL) designation. Those resources previously designated as historic landmarks prior to the UDC Amendments of June 24, 2010, will continue to bear the words "historic, exceptional" (HE) or "historic, significant" (HS) in their zoning designation.
