The village’s name first cropped up in 1438 as Aldenfeld in the Sponheim taxation book. Beginning no later than the 12th century, Allenfeld belonged to the County of Sponheim and in the 13th century was grouped into the newly formed administrative entity called the Amt of Winterburg, which as of 1416 belonged to the so-called “Hinder” County of Sponheim-Starkenburg.
As at 31 August 2013, there are 195 full-time residents in Allenfeld, and of those, 106 are Evangelical (54.359%), 35 are Catholic (17.949%) and 54 (27.692%) either have no religion or will not reveal their religious affiliation.
A particular highlight in Allenfeld is the cycle path that follows the old right-of-way once used by the former Kreuznacher Kleinbahnen, a narrow gauge railway network that closed in 1936. The path snakes its way along one side of the Gräfenbach, coming back along the other side of the Ellerbach valley. The path reaches its highest point in Allenfeld at some 370 m above sea level. Also found here is the old Allenfeld winepress, which was once used to press the fruit from the meadow orchards, which was then made into must.
