In 1884 an Autograph Book was presented to the Revd Arthur Robins (Rector 1873-1899) by the then Prince of Wales, later King Edward VII.  The cover is ivory inlaid with a silver inscribed badge (which has written on it "Given by HRH the Prince of Wales to the Revd Arthur Robins Christmas 1884").  The Prince and his family all signed the first page of the book (pictured) and it was later signed by other members of the Royal family (including Queen Victoria), many European royals (including the Tsar of Russia and his wife, then fiancee), politicians (including several prime ministers), high-ranking army officers and well known actors of the day.  Today guests staying at Windsor Castle don't usually find their way to Holy Trinity.  In 2019 those invited to attend the service marking the 175th anniversary of the church were invited to sign the book.  Most recent signatories include Dr Lucy Worsley and Gyles Brandreth, who each had an event at the church as part of the Windsor Festival.  It is a wonderful record of those who have passed through Holy Trinity's doors in the past 139 years (and we should probably mention that the book resides in a particularly secure place off-site!).
