From The BBC:
Researchers are working to uncover the mysteries of 33 wood carved medallions which would have decorated the Royal Palace at Stirling Castle.
Historic Scotland is trying to find out why the works, known as the Stirling Heads and carved between 1530 and 1544, were created and whom they depict.
The carvings are thought to feature monarchs such as James V and England’s Henry VIII.
The research is part of £12m plans to refurbish Stirling’s Royal Palace.
Historians are in the process of restoring the palace to how it would have looked in the 1540s and creating a new gallery where a replica set of heads will go on display.
…
The palace was begun by James V in about 1538 as a home for his new French bride Mary de Guise.



OK – wow!
