Today, only ruins remain of the sugar factory in Ramoni, although just over a century ago it was one of the largest enterprises in the region with a global reputation. Ivan Ivanovich Tulinoff, a prominent industrialist from Voronezh, whose family earned its status by helping Peter I build the fleet, acquired an estate in the northern part of Voronezh province at the end of the 18th century. In 1840, his son Nikolai Ivanovich established sugar production here.

For the first forty years, the factory's ownership changed frequently: among them were Tulinoff's sister, Lieutenant General Organovich, a relative of the Vyazemsky princes Velyaminov, and even the imperial court. However, the enterprise remained unprofitable and inefficient. In 1880, the factory came into the hands of the young and energetic Evgenia Maximilianovna Oldenburg (Romanov).

As the owner, she demolished the old building and constructed new facilities, implementing diffusion techniques using steam, which was advanced for the late 19th century. This allowed for an increase in production to twenty tons of sugar per day. Three years later, the production of finished products began.

By the early 20th century, the small enterprise had transformed into a major brand, producing about four hundred types of candies and chocolates that won gold medals at exhibitions in London, Paris, and Vienna. The factory became a center of infrastructure: a railway line was laid, and a workers' town with a hospital was built. A congress of agronomists from across the Russian Empire was held in Ramoni.

The energy of Romanovskaya was not limited to confectionery. She engaged in charity, supported crafts and the arts, opened new productions, and maintained a publishing house. However, her main personal brand remained the sugar factory in Ramoni.
