Both villages were part of the Waldgravial-Rhinegravial Amt of Dhaun and formed the court district (Gericht) or Schultheißerei of Hochstetten.

In 1426, the Vogt Johann von Simmern held a half share in the village and court at Überhochstetten (Hochstädten) as a fief from the Waldgraves of Dhaun.

The villages of Nächsthochstetten (Hochstetten) and Dhaun were grouped into the Mairie (“Mayoralty”) of Kirn, the Canton of Kirn, the Arrondissement of Simmern and the Department of Rhin-et-Moselle, whereas Überhochstetten – whose name was at this time changed to Hochstädten – belonged to the Mairie of Merxheim, the Canton of Meisenheim, the Arrondissement of Birkenfeld and the Department of Sarre.

Once French rule had ended in the Rhineland in 1814, the Congress of Vienna awarded the region to the Kingdom of Prussia, which took possession of it in April 1815.

The municipalities of Hochstetten and Dhaun passed in 1816 to the Bürgermeisterei (“Mayoralty”) of Kirn (later named the Amt of Kirn-Land in 1927) in the Kreuznach district in the Regierungsbezirk of Koblenz.

The municipal election held on 7 June 2009 yielded the following results:[10] Hochstetten-Dhaun's mayor is Hans Helmut Döbell (SPD).

[1] The German blazon reads: Schild gespalten, vorne in Grün zwei goldene gekreuzte Hämmer, hinten in Gold ein roter blaubewehrter und -gezungter Löwe.

The charge on the dexter (armsbearer's right, viewer's left) side, the hammer and pick, is the mark of the stone industry in the municipality.

The charge on the sinister (armsbearer's left, viewer's right) side, the lion, is a reference to the village's former allegiance to the Waldgraviate-Rhinegraviate.

Before their dissolution on 6 June 1969, the former municipalities of Dhaun, Hochstädten and Hochstetten bei Kirn bore their own arms.

[13] The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:[14] Schloss Dhaun is a castle ruin in the Hunsrück within Hochstetten-Dhaun’s municipal limits.

The Prince-Archbishop-Elector prevailed in the siege, and Johann eventually had to grant him the unhindered use of the castle in times of war or feud (an arrangement called Öffnungsrecht in German history).

One year later, the Schloss was threatened with destruction during the War of the Polish Succession, a fate then already suffered by the neighbouring Castle Kyrburg.

The buyer, who paid 1,200 francs for it, was Andreas van Recum, a high official in the French administration, the sous-préfet in the Arrondissement of Simmern.

Further changes in ownership followed until at the turn of the 20th century, a manufacturer from Kirn named Simon acquired Schloss Dhaun and undertook various new building projects and renovations on the upper bailey.

Preserved at this mediaeval castle complex now in the area of the upper bailey are ruins of Saint George’s Chapel (St.-Georgskapelle), consecrated in 1661 and the kitchen building as well as two bastions and the girding wall with defensive towers and a gatehouse.

The building was reconstructed by the Zweckverband, and since 1957 it has housed the Heim-Volkshochschule Schloss Dhaun, a training centre for youths and adults whose scholastic head for many years was the historian Werner Vogt.

At the lower bailey, the Bad Kreuznach district maintains at the site of the watchtower a youth training centre, and the great hall is available for celebrations.
