Detectorists discovered treasure four times in Cumbria last year, figures show.

The Institute of Detectorists said finding treasure gives historians a valuable insight into the past, but encouraged hobbyists to practice "responsible" metal detecting.

Figures from the Ministry of Justice for 2021 show there were four finds reported to Cumbria Coroner's Court, which is responsible for holding treasure inquests.

This was up from one the year before – ​and among 58 found in the area since records began in 1995.

Across England and Wales, 908 finds were reported last year – 13% more than the year before, but still below the record 1,061 found in 2019.

The Treasure Act, introduced in 1997, defines treasure as discoveries older than 300 years.

These include coins, prehistoric metallic objects and artefacts that are at least 10% precious metal such as gold or silver.

All potential treasure finds are processed by the British Museum, whose experts advise coroners on whether the find fits the definition of treasure.

If a coroner rules that it is treasure, both local and national museums are given the chance to acquire the pieces, and the finder will be paid a sum depending on the treasure's value.

But if the find is determined not to be treasure, or no museums want it, then it is returned to the treasure hunter.

The MoJ said the number of finds increased steadily from 1997 but since 2018 the trend has been more volatile.

It said the rise in the number of finds from 2020 to 2021 is likely due to the easing of coronavirus pandemic restrictions.

With 87 finds, there was more treasure found in Norfolk last year than anywhere else across the two nations.

The MoJ said the number of finds varies greatly across the country, most likely due to "geographical and historical differences" between areas.
