Archaeological work for the new nature area at Vlietweide in The Hague has uncovered flint tools and pottery fragments dating back nearly 5,000 years.
The city of The Hague, which announced the discoveries, called them remarkable.
Archaeologists also turned up unusual hoofprints left by livestock, along with an almost complete pot from the Iron Age.
Meanwhile, the nature area is taking shape as workers dig waterways and plant trees across the site.
Bridges, boardwalk paths and a playground are due to follow next year.
Vlietweide construction continues
Construction began in November 2025, and the new Vlietweide is expected to be finished by the end of 2027.
Vlietweide sits in the Vlietzone on the edge of The Hague and borders the municipality of Leidschendam-Voorburg.
The area covers almost 13 hectares and has been used until now as pasture for sheep and horses.
