Under the chairmanship of the ruling Prince Karl Wilhelm zu Nassau-Usingen, who also became its first Master of the Chair, the lodge "Zur beständigen Einigkeit" was founded in Biebrich Palace on August 6, 1778. The lodge only existed for a short time. In 1803, after the death of the prince, masonic life came to an end.

Finally, on May 2, 1858, the new lodge "Plato zur beständigen Einigkeit in Wiesbaden" was revived in the temple of the Frankfurt lodge "Zur Einigkeit". Like all Masonic lodges, this was a union of men of different religious, political and ideological convictions, committed to human dignity, freedom and self-determination. The name Plato refers to the association with the Frankfurt lodge "Sokrates zur Standhaftigkeit", with which Wiesbaden brothers maintained contact during the dormant period. In 1896, the lodge was able to inaugurate its newly built lodge house at Friedrichstraße 21. As the space there soon became insufficient, the brothers decided to build a new lodge house in the neighborhood at Friedrichstraße 35, which they moved into in 1896. In the 1920s, "die Plato" was a social hub in Wiesbaden. The lodge had more than 200 members at the time.

The Nazi dictatorship put an end to lodge life in 1934. After the Second World War, the first Masonic work took place on September 10, 1948. After the lodge house was destroyed in the bombing raid in February 1945, the Haus der Heimat was built on the property at Friedrichstraße 35.

In the following years, several new lodges were founded in Wiesbaden: the lodge "Mozart zur Liebe und Pflicht" was founded in 1951, an American military lodge has been operating under the name "Luftbrücke" since 1957 and the lodge "Humanitas zu den drei Lilien" since 1973. The lodge "Zur erstrebten Weisheit" was formed in 1991 and the women's lodge "Quelle zum Licht" was founded in September 1995. Today, all Wiesbaden lodges work in the lodge house at Friedrichstraße 35.
