Today, the listed building is owned by Kuwaiti investors who wanted to convert the castle into a luxury hotel.
The so-called Dagobert Tower, a pavilion with a spiral staircase from the period after 1575 that was destroyed in the Second World War, and the cellar vaults "with stone and iron doors, probably former dungeons" were also included.
[5] After being sold by the von Baden family in October 2003, the castle became the property of the Kuwaiti Al-Hassawi group of companies.
Businesswoman Fawzia al-Hassawi, daughter of the company founder, developed plans for a new use - from a luxury hotel to a vacation home for her family.
[6][7] In April 2010, the city of Baden-Baden granted permission for the conversion of the New Palace into a luxury hotel with 130 rooms, which was originally due to open in 2013.
[9] After several years of stalled construction and doubts about the financial viability of the project, Baden-Baden's municipal council decided to finally cancel the development plan on February 21, 2022.
