Many of the interior scenes were filmed at Belvoir Castle in Leicestershire. The bed used in the honeymoon scene was slept in by the real Queen Victoria when she visited the castle in 1843. The bedroom is so small that all the cameras had to be placed outside the windows.
The dress Victoria wears for her first meeting with her council is a copy of the actual dress Queen Victoria wore on this occasion. It survives and as of 26 March 2012, is on display at Kensington Palace as part of the new Victoria Revealed exhibition. It is on public display in the Red Saloon (the actual room of her first Privy Council). It has since faded to brown as the black dye at the time was not stable.
The 'seaside' scenes were filmed at Belvoir Castle, approximately 70 miles from the sea. The 'sand' is actually on the terrace (roof of the ground floor) of the castle. The surrounding Vale of Belvoir was digitally replaced with 'seawater'.
The trivia item below may give away important plot points.
The scene in which Albert is shot while shielding Queen Victoria from an assassination attempt is based on a real attempt that took place June 10, 1840. Edward Oxford, an unemployed barkeep, fired two pistols toward the Queen's carriage as she and Albert rode on Constitution Hill near Buckingham Palace. The movie, however, contains several significant departures from the facts. In real life, Albert was not injured. The court was never able to prove that Oxford had shot anything but gunpowder from his guns. Oxford was acquitted by reason of insanity, and committed to the Bethlem Royal Hospital's criminal lunatic ward. Neither Victoria nor Albert was ever injured in any other assassination attempt in their lives.
