The two-storey plastered half-timbered building with three-storey central and side risalits is based on French models in terms of its spatial structure and design and was furnished with sumptuous interior decoration. The banqueting hall is an outstanding example of 18th century courtly room decoration in Mecklenburg. In 1761 the permanent court residence in Mirow came to an end as Neustrelitz became the main residence. The family members only came to the palace for funeral ceremonies. The hereditary burial place is located in the nearby Johanniterkirche church. After 1920, the castle was used for various purposes.
It has been carefully restored since October 2005. Events and exhibitions are held in the Kavaliershaus and the Remise.
The former baroque garden was transformed into an English park in the 19th century. An arched bridge with shell limestone vases leads to the romantic "Love Island", the resting place of the last reigning Grand Duke of Mecklenburg-Strelitz.
