In celebration of the Queenâs 90th birthday, Penelope Keith, goes behind the scenes of Her Majestyâs Royal residences Penelope meets the people who uphold extraordinary royal titles and appointments, from the Royal Falconer to the Washer of the Sovereignâs hands. Itâs a world Penelope knows something about, having been at Her Majestyâs service herself, when she took up the position of High Sheriff for Surrey in 2002. Across the series Penelope heads to four corners of the union: In England, she visits Windsor Castle, meets the Royal Herb Strewer and travels in style along the Thames, in the Royal row barge with the Queenâs Bargemaster by her side. In Scotland, Penelope drops in on The Palace of Holyroodhouse and meets the Duke of Argyll, at his family seat, Inveraray Castle.
