The largest petroglyph field in Denmark is Madsebakke. The carvings date back to the Bronze Age. On a large smooth rock there are 11 ships 3 curved lines probably also representing ships, sun crosses or wheel signs, foot signs and some bowl pits. More recently, several petroglyphs have been found in the vicinity, but they are located in private gardens.

The name Madsebakke can be found as far back as 1719. The land was then owned by a man called Madtz ( Mads ) and it is he who has given his name to the area.
