Keeping the neighbours at bay.

A yett from the Old Scots word for "gate" is a grille of latticed interwoven wrought iron bars used for defensive purposes in castles and tower houses. Unlike a portcullis, which is raised and lowered vertically using mechanical means, yetts are hinged in the manner of a traditional gate or door and secured by huge bolts attached to the yett.

According to Wikipedia, and who am I to question that great authority, being a defensive structure, a royal warrant was required before a yett could be added to any house or castle. Following the Union of the Crowns in 1603, efforts were made by the government to control the disorder in the Borders. In November 1606 it was recognised that one of the impediments to the administration of justice in the area was the strength of the houses. Consequently, the Privy Council ordered that all yetts should be removed from all houses belonging to those lower in rank than barons. Perhaps if we vote for independence next year we lower ranks might once again be able to install a yett. Now, where did I put my furnace and anvil?
