The National Portrait Gallery has a new display of a set of portraits of Kings and Queens.

You can also view some of the paintings at the BBC History Magazine website.

Usually on display at Montacute House in Somerset, they are worth seeing. I visited Montacute House in 2008 and 2009 to see On the Nature of Women Exhibition which included a portrait of Lady Jane Grey.
