The castle, designed by German architect Rudolf Müller in the style of late neo-Gothic, also includes elements of Gothic, Eastern, Romanesque, and ancient Russian styles. The combination of red and black brick with white stone details is mesmerizing. The southern entrance leads to a winter garden with a glass dome. Architects Alexander Stern, Alfred Parland, Sergey Rodionov, and Pavel Malinovsky participated in the construction of the castle.

The rooms of the castle had their own purposes. Among them stands out the office of General Skobelev with a rich collection of weapons. The interior of another hall, decorated in Eastern style, resembled Persian design. It features colorful marble columns from Italy, a marble floor with patterns, and Arabic paintings. There is also a Picture Gallery and an Oak Room. All former lordly rooms were connected by special passages with spiral staircases.

The Sheremetev estate has a large park area. Tourists are impressed by the architecture and decor of the Mikhailo-Arkhangelsky Cathedral, which has no analogs on the left bank of the Volga. From above, the temple resembles a cross.

The castle is located in picturesque natural surroundings, near the Volga and Vetluga rivers, surrounded by pristine forests of pine, oak, and birch, which attracted Russian artists, writers, and historians. Vladimir Korolenko and Ivan Aivazovsky have visited here.

Currently, the estate is being restored, and part of the premises is used as a hotel complex. Staying in a 19th-century castle is interesting in itself. It seems that time flows differently here, everything is soaked in history.

The staff of the museum complex has developed an exciting excursion and tourist program. Traditional and interactive tours are conducted in the main house of the Sheremetev castle, the estate, the Mikhail Archangel temple, and the forest park area. Individual tourist services have been introduced. Master classes in folk art are popular. Children's, New Year, and Christmas programs will leave no one indifferent.
