The Græsholmene dolmen, located in the Græsholmene forest in Svendborg, is a Stone Age long dolmen, with its origins dating between 3950 and 2800 BC. The site was reconnoitered by Svendborg Museum in March 2011 as part of a museum reconnaissance, under journal number SOM 427.
The archaeological complex consists of a 30-meter (North-South) by 11-meter (East-West) earth mound, which is 0.6 meters high. It features a collection of large stones arranged in two groups, alongside other large stones situated individually but in close proximity to the main groups. Smaller stones are found along the long sides of the mound, with larger stones concentrated at its northern and southern ends. The largest stone in the northern end measures 170 x 110 cm, while the largest in the southern end is 190 x 150 cm.
Archaeologists believe these are likely the remains of two chambers. A significant discovery during the investigation involved a fallen tree in the southern stone collection, which exposed a bearing stone. From the disturbed soil immediately west of this bearing stone, four flint flakes were collected. Moss grows on many of the stones, and a small earth mound is present near one of the stone groups. The entire complex is easily accessible from a main forest road via a side road. The responsible museum for this site is Arkæologi Sydfyn (Svendborg Museum).
