They are a particularly charming feature of the urban fabric of Amsterdam, and are also found in cities such as Brussels, Lille and Copenhagen. Some 2,500 of these stones are still to be found in the Netherlands, of which around 850 are in Amsterdam and 250 in Maastricht. Many have been conserved by the VVAG(Friends of Amsterdam Gable Stones).
Gable stones came into use in the 16th century, in the days before house numbers, taking over from hanging signs as a way of simultaneously and memorably identifying and adorning a house. They normally combine a picture with an inscription, or sometimes just a date. Some illustrate the name or profession of the owner, for instance a quill pen as a badge for an author, or a ship for a sailor. Some are named after notable people (The King of Bohemia) or faraway trading destinations (Königsberg). Some stones act as talismans, quoting from holy scripture. A pious motto repeatedly found on Dutch gable stones is Nooit Volmaakt (Never Perfect), a testimony to the householder's belief that only God can achieve perfection. Going beyond practicality or superstition, some stones make a joke, usually a visual pun.
A variation on the theme is a tablet bearing a biblical quotation or more worldy motto, but without an image. (Mediaeval builders also often carved mottos in wooden beams or painted them on plaster panels.) An interesting example is the Dutch-language tablet in Österlånggatan in the Hanseatic old town of Stockholm, Sweden. It reads:
The tradition is alive and has moved with the times – new stones are still commissioned, and for instance the Rabobank at Frederiksplein 54 in Amsterdam wistfully commemorates the introduction of the euro with a stone entitled De eerste en de laatste gulden (The first and the last guilder), created by Zutphen sculptor Hans 't Mannetje Nowadays one can even buy a new gable stone off the shelf on the web!
