Gammel Hestehave Rundhøj 411712 is classified as a Round Barrow located in Denmark, specifically in Fyn, near the town of Svendborg. It is identified as a site from the Neolithic and Bronze Age. The site is a national heritage monument, protected since 1937 or later.
The mound is noted for being impressive. It is considered one of the best-preserved mounds in the area and is the second largest in terms of height and diameter.
The mound has a total height of 3.5 meters and a diameter of 25 meters. An inspection in 1983 recorded its dimensions as 3.0 meters high by 28.0 x 25.0 meters.
At the foot of the mound, there is a row of curbstones. Above and beside these curbstones, steps have been made, resembling stairs. A small natural path leading to the top is visible due to foot traffic. A large tree grows on one side of the mound. Historically, the mound was described as being covered with grass and fruit trees.
The mound is situated next to a neolithic burial cist (stenkiste).
The mound was historically utilized as a platform for a water tank or water tower dating to the Newer Period (1900–1949 AD). Its placement on the top of the mound was thought to have only damaged the surface superficially.
By 1983, the water tower had been removed, though its round concrete foundation could still be discerned. The stone steps on the eastern side near the top, along with a stone setting at the eastern foot of the mound, are believed to be remnants of a garden facility or landscape feature.
The site has been subject to continuous monitoring and supervision by various authorities, including the National Museum (1947) and Museum Odense (2016, 2019). In 2010, it was designated as a monument of national importance.
