In 1582 Anton Fugger acquired the rule of Hainhofen and the associated moated castle from Gabriel Rehlinger. The complex, consisting of a high and long lock, was built by him in a Renaissance style. Anton Fugger also had a chapel built. In 1601 Anton Fugger sold the property to Wolfgang Paler the Elder. J., who, as a Protestant, had the chapel torn down. Paler's daughter Magdalena married Max Karl Rehlinger in 1602 and the castle came back into possession of the Rehlinger family . After an eventful history, the castle was finally returned to the Rehlinger family. The current appearance of the high palace results from a comprehensive renovation around 1730:
- At that time the bay windows were removed, the gable roof replaced by a hipped roof and the east side accentuated by a gable with a curved end. A risalit built on to the west conceals the spacious staircase. A hall was set up on the upper floor and decorated with delicate ceiling stucco.
Another major modernization took place in the last quarter of the 18th century. The strict separation between high and long lock was removed by means of a connection:
- The latter has since appeared as a two-and-a-half storey building under a flat hipped roof. The alliance coat of arms of the builders, Joseph Karl Freiherr von Rehlingen and his second wife (married in 1776) Franziska Countess von Welsperg-Primör, is placed in the gable above the western gateway. The 19th century saw the establishment of a small castle chapel in a western room on the first floor in 1854.
The castle remained in the possession of the baronial Rehlingen family until the 1930s, then came through the marriage of Emilie von Rehlingen to the Reichstag deputy and SS standard leader Rolf von Humann , who leased the properties and initially rented the high castle to the workers' welfare, then (in the 1950s) set up a refugee home ... Later a castle café and a beauty farm were housed here . Rolf von Humann's heirs finally sold the property to a private individual in 1970. In the following years, the area was rented to the Order of the Knights Templar and then to the Bhagwan sect until 1983 . Hainhofen Castle has been in shared private ownership since 1988. The recently very dilapidated building complex has recently been extensively renovated. In 2014 the castle received the Schwaben District Monument Prize for an exemplary perfect renovation .
