Horsens was then a busy commercial city. In particular, it performed with Hamburg, Lübeck, Bremen, Bergen and Amsterdam. It was therefore quite natural that most inhabitants were engaged in trade and crafts.
Gerhard de Lichtenberg belonged to both his mother's and father's active trade fairs. His father, Hans Christensen, was a well-known trader who had progressed step by step to become a very wealthy man.
Hans Christensen acted extensively with a flank castle named Heinrich Lichtenberg whose sister Gedske married him in 1695. The marriage lasted only shortly before April 9, 1697, the wife gave birth to his famous son Gerhard de Lichtenberg, and this cost Her life.
After graduation and education at the uncle in Flensburg, after whom Gerhard took his last name, he married in 1728 with Bodil Hoffgaard. This marriage brought him into Horsens' finer circles and gave him more capital to work with.
Gerhard had taken over both his uncle's and his father's business as quite young. When the business gained a recovery, he took over his first farm "Lindebjerggård" in Ølgod, north of Varde, in which he had a mortgage in 1731. This was the start of a large number of acquisitions of properties around Jutland. The crown of the work was "Bidstrup" at Randers.
In Horsens he built a beautiful residence, one of the country's most beautiful and beautiful oldest town houses. Here there was a tall timbered building with wide twigs and a beautiful carpentry. Lichtenberg made it converted in 1744, so that the farmhouse facing the street was given its present shape as a ground-walled palace building in two logs and with a high basement. At the center of the front was a twig and on each side of the high stone staircase a protruding carnival that rises through both floors and ends in half-round and roof-shaped stone quarters. Over the richly decorated sandstone portal you can see Lichtenberg's coat of arms and below you can read: "Was good protected unless nobody wehrt, anno 1744". All the windows of the house have frames and beautiful stone finishes. Inside the house are rococo ceilings, and doors and brass locks in the same style.
Nicolaus Reimann was Lichtenberg's architect, both in the palace and in other of his buildings. The Lichtenberg Palais is a pure gem in Danish building art and created for the city hall, more beautiful than most modern townhouses and more stylish than many modern ones.
Due to his great work, Gerhard de Lichtenberg was also noted in the royal circles. King Frederik the fifth honored him with a visit to which the ever-existing royal chair was built.
Lictenberg died on July 19, 1764. He is buried in the monastery of Horsens, where Bodil de Lichtenberg was buried at his death 30 years later.
In 1813, the palace became a guesthouse and has been up to today.
