Over the years, Hollywood has produced countless films centred around a defiant search for one of the world’s long lost treasures. From the Ark of the Covenant to One-Eyed Willy’s treasure, these items seem to be shrouded in mystery only to be found on a whim by a devoted group of explorers.  But in reality, the world of treasure hunting is seemingly much less rewarding, with many of the most prized possessions of the ancient world still waiting to be found. And unsurprisingly, given its rich tapestry of Kings, Queens, wars and revolutions, there are a number of treasures from the past hidden across the UK. Here MailOnline retraces some of the most well known – including royal gem stones, precious crowns and even Spanish loot – and where they might be recovered.  This graphic shows some of the most well known of Britain’s treasures and where they might be recovered Lord Nelson’s diamond Chelengk jewels have not been seen since they were stolen in 1951 The Imperial State Crown is a priceless symbol of the British monarchy. But the ones currently on display are not the same as those from several centuries ago, which are thought to have been lost in The Wash in East Anglia Llywelyn’s coronet Llywelyn ap Gruffydd, or Llywelyn II, was the Prince of Wales, from 1258 and is known for leading a campaign against King Edward I of England. Before going to war against the King, Llywelyn left his crown under the protection of a group of monks at Cymer Abbey in Gwynedd. However he was unable to retrieve it, after meeting is end at the hands of King Edward I’s men in 1282. Two years after his death, the crown was seized and taken to Westminster Abbey in London. It was kept by King Edward I as a token of Llywelyn’s defeat, which also represented the end of any hopes for an independent Welsh state. The crown was then kept in the Abbey alongside the English Crown Jewels, before being moved to the Tower of London in 1303. It is then thought to have been destroyed on the orders of Oliver Cromwell in 1649. Although others believe the crown was removed from the Tower of London prior to this, meaning they may still be lost somewhere in the UK.  Llywelyn ap Gruffydd, or Llywelyn II, is seen in a painting with the Archbishop of Canterbury, King Alexander III of Scotland Oliver Cromwell who is thought to have ordered the destruction of the Llywelyn’s coronet in 1649Admiral Lord Nelson’s chelengkAdmiral Lord Nelson was gifted the stunning seven-inch chelengk by Sultan Selim III of Turkey after the Battle of the Nile in 1798.Nelson was the first non-Muslim recipient of the chelengk and wore it on his hat like a turban jewel, sparking a fashion craze for similar jewels in England. It remained in his family for generations before it was sold in 1895 for £710 to ease the family’s financial difficulties.The chelengk was then bought for £1,500 by the Society for Nautical Research in 1929 following a national appeal and placed in London’s National Maritime Museum.But it was stolen in 1951 by career criminal George Chatham, who sold the jewel for a ‘few thousand’ to a criminal gang who he believes broke it up into little pieces.More than 50 years on from the theft, London jeweller Philip Denyer decided to pay tribute to Lord Nelson by creating a replica of the chelengk in 2017. He used 350 18th century diamonds to make thne replica, which was then put on display in the Victory Gallery at Portsmouth’s Historic Dockyard alongside a black felt cocked hat.

Picked it up, turned it up, Emeralds!’Tucker later sold it to the Government of Bermuda for $100,000 in 1959, meaning that it stayed on the island where it was kept in the Aquarian Museum. Shortly after the sale, the cross was stolen from the museum and replaced with a cheap plastic replica. It came just days before Queen Elizabeth II’s was due to visit to the museum, with the replica cross removed from the display by the time she arrived.  A replica of the emerald containing Tucker Cross displayed at the Ocean Discovery Centre in Bermuda after the real cross was stolen in 1959
