Königshofen (Niedernhausen), Kr. Rheingau-Tanus, Hessen
After the Peace of Westphalia in 1648, Count Johannes of Nassau-Idstein settled Catholic Walloons from the Prince-Bishopric of Liège in several areas including Niedernhausen, Königshofen, and Engenhahn. He allowed these settlers to keep their Catholic faith even though they were in a Protestant territory. Today, this territory is in Hessen, and Königshofen is part of a larger administrative unit headquartered in Niedernhausen.
