Treasured City

In September 2016 Luke visited North Lincolnshire Museum and selected 5 small artefacts that he and the curator felt represented the region. The objects span a period from ancient through to modern times. Each object was then 3D scanned, 3D printed in wax and then cast in 18ct gold. The gold replicas, each worth at least £2500 were then hidden across Scunthorpe and the region for the public to find and keep.

Clues to the whereabouts of the 5 gold artworks were woven into the visual content of 5 paintings for exhibition in 20-21 Visual Arts Centre from 18th February –  29th April 2017. Luke worked with a code breaker from GCHQ to set the visual clues within each painting.

The paintings in the exhibition ranged in difficulty. One painting was “so easy to solve even a child may be able to work out the location of the golden treasure”. Whilst other codes were far harder to crack.

Films and photos of the process of scanning and  documenting the fabrication of the golden replicas, were displayed at 20-21 Visual Arts Centre as a part of the exhibition. In this way the arts project reanimated and celebrated the history of the original artefacts and the region.

Luke said “For me, Treasured City is a creative treasure hunt. A playful fusion of history, craftsmanship, mathematics, code breaking, poetry and painting.”

“I like the idea that ancient objects that were once hidden beneath the earth and were discovered and displayed at the museum are now being re-hidden. I hope the public will enjoy visiting 20-21 Arts Centre and exploring the town and surrounding countryside.”

Treasured City was commissioned by 20-21 Visual Arts Centre, Scunthorpe with funding from the Arts Council of England.


Upon finding a golden artefact, the member of the public got to keep the object. At the end of the exhibition, each of the 5 coded paintings were then given away to public institutions in the area as a legacy.

Five Artefacts

The five objects selected from the museum, are from different time periods spanning from the modern era, through Tudor, Viking and Roman times, and all the way back to the Jurassic era.

The first object chosen by Luke is an intricate 16th century Ivory Fisherwoman figurine which was discovered in a garden on West Street in Winteringham. At 6cm tall, the figure is carrying two fish in her left hand, indicative perhaps of Winteringham’s location north of Scunthorpe on the banks of the Humber Estuary.

Luke said. “I love this object. It has been so well carved with all the tiny details and is somehow intimate and personal. I wonder how many people have owned and held this object – why was it made and who for?”

The second object cast in gold is the recognisable Janus train used in the steelworks of Scunthorpe for transporting materials across the site. The ‘two-faced’ train was chosen by Luke as it represents the Scunthorpe steelworks which has dominated the town and its history.

Representing Scunthorpe’s ancient geological history, an ammonite is the third object in the Treasured City hunt. Ammonites with their typically ribbed spiral shell form are perhaps one of the most recognisable fossil types, with their name originating from the Greek ram-horned god Ammon. Ammonites belong to a group of predators known as cephalopods, which includes their living relatives the octopus and squid, and they lived in the sea between 240 and 65 million years ago.

A beautiful Viking brooch is the fourth item that Luke has cast into gold, selected to pay homage to the region’s Viking history. The brooch, which was discovered by a metal detector in Ewerby, is a typical trefoil shape and is decorated with interlaced animals in a Borre style. Trefoil brooches such as this were traditionally worn by Viking women. In the 9th Century, Vikings raided the North East coast of Britain ahead of a full scale invasion in 866AD. After crossing the Humber, the Danes sacked and captured York; traditionally a great defensive stronghold, despite fierce Northumbrian resistance.

Luke said:  “The brooch has such a strong and dynamic form. Its shape reminds me of all the wind turbines there are in the area. I wonder how many people have worn it over the centuries? ”

The final object is a small 3cm copper alloy ram figurine, believed to be 1st century Roman. Discovered in Winteringham like the Ivory Fisherwoman, the exact origins of the figurine are unknown but it is believed that it may represent a sacrificial ram within a household or temple shrine, or may even be a simple child’s toy.

Luke said “I chose this object as I know that farming and agriculture has always been important in the region. I like the fact that we don’t know exactly why the object was made or what it was for.”

BBC One Show discusses the projects and some of the paintings solved.


With thousands of people visiting the arts centre to see the exhibition the art project was considered a great success.  Many local people visiting the show had never been to the arts centre before and for weeks, it became the ‘talk of the town’.  Many visitors travelled from across the country to see the exhibition.

The artwork gained extensive news coverage both locally and nationally, which promoted Scunthorpe in a positive light, as a town where exciting and creative things can happen.

Each of the paintings in the exhibition are being given away to organisations in the area where they will be on public display.

Re-animating the original artefacts from the North Lincolnshire Museum, many people went to find these objects, drawing visitors to this museum as well.
