Langenselbold Castle was built by the Counts of Isenburg-Birstein (princes from 1744) in Langenselbold between 1722 and 1752 (with interruptions).
The building site was the site of the Premonstratensian monastery of Selbold, which was dissolved in 1543.
The architect was the master builder of the County of Hanau, Christian Ludwig Hermann, who worked on this project and on the parallel building project for the Evangelical parish church of Langenselbold for Count Wolfgang Ernst zu Isenburg-Birstein.
The complex consists of six individual buildings, some of which are grouped in pairs around the four sides of a courtyard measuring 95 × 127 m.
A baroque garden was originally laid out here, the central fountain of which was later moved to Birstein Castle.
On the eastern and western long side of the courtyard are barns and coach houses, on the southern narrow side there is a building that used to contain servants' quarters and is now used as an inn.
All of these buildings are single storey.
Two two-story buildings with mansard roofs form the north side of the complex.
The western one, from 1722, is the oldest in the complex and served as a fruit store.
The eastern one, from 1749, is the youngest of the ensemble and was the manorial residential building.
Inside there are several rooms with rococo furnishings, silk wallpaper and paintings from the time it was built, including a portrait of the Elector-Archbishop Clemens August of Cologne by George Desmarées and one of Landgrave Wilhelm VIII of Hesse-Kassel by Johann Heinrich Tischbein the Younger .
Another part of the equipment comes from the circle around Johann August Nahl.
Christian Ludwig von Isenburg-Birstein moved into the castle in 1757 after retiring from military service.
His father, Count Wolfgang Ernst, took care of the furnishings.
In 1940, the city of Langenselbold bought the Fruchtspeicher and converted it into the town hall after the Second World War, and in 1976 it bought the rest of the facility.
A lifelong right of residence remained for some members of the royal family. This included the art historian Princess Margaret of Isenburg.
The former manorial residential building now houses the municipal library, meeting rooms and a banquet hall.
