At the centre of the Hardenberg estate and at the foot of the historic Hardenberg castle ruin lies a refuge full of classic elegance and rural idyll, unspoilt nature and modern comfort: the Hardenberg BurgHotel. Whether for an unforgettable weekend with the family, as a couple, for a dream wedding, a round of golf or a meeting with business associates: In this 5-star hotel, nothing is left to be desired.

The Relais & Châteaux Hardenberg BurgHotel offers joie-de-vivre, bliss and relaxation of the highest quality and always with a personal touch. This is what our director Isabelle Rosentreter and Relais & Châteaux, which specializes in individual luxury hotels, and of which the Hardenberg BurgHotel has been a member since 1999, stand for. The Hardenberg BurgHotel has furthermore - since February 2018 - been part of the FEINE PRIVATE HOTELS, an association of hotels that stand for luxury, lifestyle and charismatic personality.


Behind the concept is Carl Graf von Hardenberg, who now leads the company in its ninth generation. " I vouch personally for the quality of Hardenberg products with my name," says Carl Graf von Hardenberg, who sees it as his duty to interweave over 300 years of history and tradition with a viable future vision. The wild boar head - the heraldic animal of the Hardenberg family - is not only the trademark of Hardenberg-Wilthen AG, but also stands for the Counts' Hardenberg estate.
