In 1189, the lordly estate of Sigilovf(e), meaning glistening brook, and out of whose name arose the placename Sailauf, had its first documentary mention. In the 13th century, Sailauf was for a short time ruled by the Counts of Rieneck, who built the castle Landesere on the nearby Gräfenberg. In 1265, the Archbishop of Mainz, Werner von Eppstein built the hunting lodge castrum vivarium, which was later renamed Weyberhof. When the Plague raged in Europe in 1349, the Vorspessart was all but emptied of people. Newcomers later came to Sailauf from the Steigerwald. In 1552, Schloss Weyberhof was destroyed.
