Barkov Mill in the village of Novoivanovka, Volokonovsky District, Belgorod Region, Russia, is a unique steam mill building, a monument of architecture from the late 19th century. It is the only six-story log building from the 19th century in the region, accompanied by three similar barns.

The Novoivanovka water mill on the Oskol River has six floors made of calibrated larch logs without the use of nails, with all joints made using wooden dowels. The foundation is built on lime, possibly with the addition of egg white.

There is a version that the mill operated on a water wheel: water from the river flowed into a sleeve, driving the wheel, from which energy was transmitted to the millstones through shafts and belt drives. Downstream, there was a dam, as evidenced by the chalk extraction on the bank. Another version claims that there was a water mill at this site before, and the current one was originally steam-powered.

After World War II, a diesel and electric motor were installed at the mill. There are still plaques indicating that the equipment was manufactured in the early 1950s by the Voronezh Mechanical Plant. Grain for milling was brought from nearby villages.

About 120 people worked at the mill, many of whom lived nearby. It produced about 100 tons of flour per day, with bags loaded at 70 kg each. To start the mill, at least 5 tons of grain had to be loaded. Flour from this mill was in high demand.

The history of this mill, dating back to the late 19th and early 20th centuries, is not precisely known. According to legend, at the beginning of the last century, merchant Barkov won it in a card game from a local landowner. Initially, the mill stood in the village of Pogromets but was moved to Novoivanovka.

The owner of the mill was merchant Mikhail Konstantinovich Barkov. His estate was located near the mill, where an old garden has been preserved. Vineyards surrounded the mill, as these places were famous for wine, and there were distilleries in the villages of Korovino and Novoivanovka. The date 1914 is burned into one of the barn logs, which may indicate the year the mill was moved from Pogromets.

After the 1917 revolution, the building was transferred to a local collective farm. In the post-war years, the mill was reconstructed, replacing steam with electricity.

The mill served for over a hundred years, with the last flour being milled here in 2004. A major renovation was conducted in 1990. Since 2004, the mill has been recognized as a monument of 19th-century architecture and is protected by the state.

The wooden Barkov Mill has become one of the tourist symbols of the Volokonovsky District. Currently, a kayaking route has been developed along the Oskol River, including a visit to the mill.
