The central element of the large architectural ensemble is the Palace, a unique monument that has preserved some original interiors to this day. These elements, along with archival photographs presented at exhibitions, allow us to recreate the lost details of the interior decoration and imagine the man-made beauty of this unusual noble nest in the heart of provincial Russia.

The exact author of the palace project is unknown, and there is no reliable data on this. Historians and local historians mention architects Nikolai Benois, Inronim Kitner, Ferdinand Miller, and Christoph Neisler, who was appointed the supervisor of works on this unique object.

In 1878, Princess Evgenia Maximilianovna Romanovskaya, Duchess of Leuchtenberg, acquired the estate in the village of Ramoni, Voronezh province. In 1883, construction of the castle for her and her husband began according to the project of architect Christoph Neisler. Within three years, walls one meter thick were erected, and by 1887, the interior finishing was completed.

The palace was built in the "Old English" style. Opposite the main house were gates with a tower and clocks from the Swiss company "Winter," called the "Svit'skoy Corps," where the retinue accompanying noble guests of the estate was housed.

The princess actively improved life in the village. She founded the first candy factory in Russia with steam machines, which became the predecessor of the Voronezh confectionery factory and received numerous international awards. The village also saw the construction of a water tower, servant houses, a dining room, a clinic, and a railway. Thanks to these changes, Ramoni transformed from a backwater settlement into a thriving place.

In 1901, Evgenia and Alexander of Oldenburg's son, Peter, married Olga, the sister of Emperor Nicholas II. A mansion named "Cozy" was built as a gift for them, but Olga did not like it, and they acquired a neighboring estate, later named Olgino.

After the October Revolution, the castle's owner was forced to flee to Denmark and then to Canada. The estate was ravaged by a manager named Koch. After the revolution, it housed a barracks, a school, a hospital, and a factory management office.

There is a legend that during the war, German troops refused to bomb the castle due to the German roots of its owners, distributing leaflets that read: "We will not bomb the palace." Locals hid in it during bombings.

Today, the palace is still majestic, despite the years that have passed. The princesses and princes have long left the land of Ramoni, and their lives seem like a distant history. However, the empty house, as if rooted in the ground, awaits change. In 2014, a museum and historical-cultural center "The Oldenburg Palace Complex" was established. In the same year, the project "Romanovs. Oldenburgs. Return through the Century" was held, timed to the 100th anniversary of Emperor Nicholas II's visit to Voronezh with his daughters.
