Installed as part of the art project "Hidden Past" following the redevelopment of Dokkum's city center. The cast-iron shell-like shape features the contours of the old city walls. The city's coat of arms, with moon and stars, is depicted in the stainless steel countershape. Sunlight shines through the shell's cutout, forming a kind of sundial inside the cast-iron shape.

Dokkumer Nieuwe Zijlen is a hamlet in Friesland, known for its historic lock complex and harbor. Designed by Willem de Loré, the complex included a drainage sluice and a navigation lock, which once played a vital role in water management and shipping between the Frisian inland waterway and the Wadden Sea. Although the locks lost their function as sea locks after the damming of the Lauwerszee, they remain important for water drainage and are a national monument.

On Hellingstraat stands a replica of a lime kiln. Built in 2015 by the Zoutkamp Historical Fisheries Foundation, people from the reintegration program participated in the project. In the second half of the nineteenth century, Zoutkamp had two lime kilns, which together formed a so-called limeworks. Around 1900, the characteristic shapes of these kilns, along with the Reformed Church, largely defined the village's skyline. Initially, Zoutkamp's business revolved around the supply of shells to various lime kilns elsewhere in the northern Netherlands. These shellfishing companies dumped shiploads of shells, primarily cockles, in large piles on the banks of the Hunsingo Canal. In the 1860s, the Zoutkamp entrepreneur Woldringh built two lime kilns on the site. Woldringh had previously also built a Portland cement factory and a steam-powered sawmill. In the lime kilns, shells harvested from the Lauwerszee and Waddenzee were calcined and then converted with water into slaked lime, suitable for mortar, plaster, and other applications. Shell fishing remains a major industry in Zoutkamp. The shell dredger De Vertrouwen, owned by the Rousant company, still regularly docks at the Reitdiepskade to unload shells. The shells are no longer used for mortar, but are primarily used for insulating and regulating moisture in houses and paving cycle paths.
