The Silverdale Hoard is one of the largest Viking hoards discovered in the UK. Consisting of over 200 items it was found by a metal detectorist near Silverdale, Lancashire in 2011. The collection includes arm rings, finger rings, ingots, coins and many other fragments of broken silver jewellery. These silver pieces may have been used as currency or were intended to be melted down for reuse.

The hoard was buried for safe keeping in a lead container between AD900-910 during a period of intense conflict between the Anglo-Saxons and Danes in the north of England. The range of items from Frankish, Anglo-Saxon and Islamic coins to jewellery with Irish, Carolingian and Russian influences, attest to the wide network of trade that the Vikings had stretching across Europe and into Asia in the 10th century AD. The hoard also contained a coin featuring a previously unknown ruler of Northumbria named Hartacut, who ruled over a vast area of northern England which included what is now modern-day Lancashire.

Sixteen Viking hoards have been discovered in the northwest, more than any other region of England. The largest Viking hoard found in Western Europe was also discovered in Lancashire at Cuerdale near Preston, which consisted of more than 8000 items.
