A gable stone is a motif of architectural sculpture with a mnemonic* function. It is a stone tablet set at a certain height in the facade of a house or building, elaborated with sculpture and an inscription: representing as such a sign which intent is address indication, admonition or notification.

*Mnemonic: method to associate notions by the aid of various devices in order to support the memory.

The gable stone developed in the second half of the 16th century mainly in the Dutch speaking regions from a much older medieval tradition to be met with all over Europe, concerning all sorts of characteristics, signs and figurines that served as address indications to houses and buildings. Street numbering was only introduced in the Netherlands around 1875.
