The residential village also lies just west of the junction of two valleys, the Simmerbachtal and the Wahlbachtal, and about a kilometre east of the Simmern-Koblenz road.
At the nearby Weißmühle (“White Mill”), three brooks, the Simmerbach, Benzweilerbach and Wahlbach, all meet and flow together.
It can, however, be assumed that there was settlement within Pleizenhausen’s current limits much earlier, for to the southwest of the village, remnants of an old Roman villa rustica are still being found in the fields even now.
In 1263, the Knights Eberhard of Sütersten sold Pleizenhausen’s wet meadow to the Kumbd Cistercian convent.
In 1500, there were 20 farmsteads, and jurisdiction was shared among the Electorate of the Palatinate, Sponheim-Kastellaun, the Lords of Stein Kallenfels and the Schmidtburgs.
Farther south, the Catholics built their own church in 1772, a chapel that still stands today, also consecrated to Saint Wendelin.
Between Bergenhausen and Pleizenhausen lay a camp run by the Nazi Reichsarbeitsdienst, which was utterly destroyed by bombing in 1945.
