On 21 May 2021, at around 10.30pm local time, a set of rosary beads (pictured) that Mary Queen of Scots carried to her execution in 1587, along with gold and silver artefacts including Mary's coronation cups, were stolen from Arundel Castle in West Sussex, England. The stolen items were worth as much as £1 million ($1.3m) in total, although a castle spokesperson described the haul taken by the thieves as "priceless".

The thieves are yet to be found, but are thought to have entered Arundel Castle through a window and smashed a glass cabinet to steal the treasures. An abandoned vehicle that had been set alight in the nearby town of Barlavington, about 20 minutes' drive away, has been identified by local police as "linked" to the crime.
