In heraldry the temple is a majestic emblem of sacred sanctuary, profound wisdom, and the preservation of divine or civic truth. As a structure dedicated to the highest ideals, it represents a person or institution that serves as a cornerstone of faith, learning, or justice within their community. Symbolically, the temple suggests a character of architectural integrity—someone who is built on solid foundations and provides a refuge for the mind and spirit. It signifies a guardian of traditions and a builder of lasting legacies, embodying the stability and permanence of the principles it houses.

The temple is frequently associated with religious orders, academic institutions, and high-level judicial bodies. It is a common charge for the arms of abbeys, cathedrals, and universities, where it represents the pursuit of spiritual or intellectual enlightenment and the "shrine" of knowledge. In civic heraldry, a temple may commemorate a city’s ancient heritage, particularly in Mediterranean or European regions with classical ruins, or it may symbolize the "temple of justice" in an administrative center. It also appears in the heraldry of fraternal and chivalric organizations, such as the Knights Templar and related orders, where it alludes to the historical and spiritual defense of sacred sites.

A heraldic temple is typically depicted as a classical or gothic structure with visible columns, a portico, and a roof, often rendered in gold or silver to emphasize its exalted status. It may be shown with a specific number of pillars to represent foundational virtues—such as prudence, justice, and fortitude—or "opened" to show an inner light or a sacred object. Variations in architectural style can indicate a specific geographic or cultural anchor, such as a Greek temple for a philosophical school or a domed structure for an Eastern influence.
