From the city of Lund in the Swedish province of Scania via the Höjebro bridge to the village Genarp at the foot of the Romeleåsen ridge, an old route called Kungsbetet "The royal pasture" can be traced on land survey maps from the 18th century. The route was over 20 kilometres long and consisted of a usually 50 metre wide ground strip owned by the king and the crown. When it is first mentioned in the early 17th century it was already in dissolution. According to different sources it is obvious that Kungsbetet was an unusually long and broad cattle path. It has hitherto not been possible to find any real counterparts. In this article the dating, function and origin of Kungsbetet are discussed. It is argued that it is from the Middle Ages and was established due to lack of pastures in Lund and in the surrounding countryside. However, vast pastures were available on the Romele åsen ridge. This old common (Sw. allmänning) was under royal control from the early Middle Ages.
