Dinosaurierpark Münchehagen, Outdoor dinosaur museum in Münchehagen, Germany

Dinosaurierpark Münchehagen is a privately run open-air museum in Münchehagen, a district of Rehburg-Loccum. A roughly 2.8-kilometre circular trail runs through the Palaeozoic, Mesozoic and Cenozoic eras, lined with more than 400 life-size static models of prehistoric animals (as of 2026), created under scientific advice. The largest is a Seismosaurus about 45 metres long. A long, low building with a shallow reddish-brown roof and a continuous row of tall glass panes stands at the edge of a pond containing large dinosaur figures.

Fossil dinosaur footprints in the Rehburg hills were already documented in scientific publications in the mid-19th century, within the area of the Wesling quarry, in operation since 1925. A provisional shelter went up over part of the track-bearing ground in 1980, and the site was fenced in 1987, shortly before it became a nature monument. Ferdinand Wesling sen. and Bernd Wolter founded the Dinosaur Park company and opened the open-air museum in 1992; the large protective hall, funded by the state of Lower Saxony with the district of Nienburg and the Lower Saxony Savings Bank Foundation, followed in 1993.

The park's Paleo-Camp lets children dig out an artificial dinosaur skeleton and search for fossils and semi-precious stones, while painting and craft activities also revolve around prehistoric animals. In a preparation workshop open to view, original dinosaur bones are cleaned and prepared, mostly from the dwarfed sauropod Europasaurus.

The visit is best enjoyed on dry days, since the path crosses natural terrain and can become slippery after rain. Sturdy footwear and weather protection are recommended, along with allowing plenty of time for the several-kilometer walk.

The park's Seismosaurus model measures about 45 metres, making it one of the largest dinosaur reconstructions worldwide. It stands among more than 400 life-size static models arranged along a 2.8-kilometre circular trail that runs through the Palaeozoic, Mesozoic and Cenozoic eras.
