In Konstantinovka, Saratov region, on the banks of the Latryk River, one of the largest mills in the region, built in 1909, has been preserved. This four-story building has a U-shaped form with tower-like projections on the main facade and a one-story rectangular volume at the back. The facades are executed in an eclectic style with elements of Gothic and castle architecture, adorned with brick decor, including corner pilasters, cornices, and arched windows. Unfortunately, the building is in a state of disrepair.

The mill was built by German settlers invited by Catherine II. In Konstantinovka, there are also buildings associated with German colonists. Documents from the late 19th and early 20th centuries contain discrepancies that make it difficult to determine exactly who built the mill. However, it is rumored to be attributed to the Borel family, who succeeded in the milling business. The structure is known as "Borel's Mill."

For those interested in history, an analysis of documents presented in the act of state historical and cultural expertise of the cultural heritage object "Borel's Mill, 19th century," located in Konstantinovka, will be useful. It is officially believed that the mill was built by the Borel family, but the documents indicate otherwise.

There were many mills on the Latryk River, both water and wind. In 1589, mills existed in every village, but there is no data on the mill in Konstantinovka, possibly due to its location beyond the floodplain meadows. In 1842, K.E. Reineke and the Schmidt brothers rented the mill from Prince Kochubei and later acquired land in the Saratov district. E.I. Borel became the owner of the land plot on the Latryk River, where other buildings later appeared.

The Borel and Kindsfater families were related and jointly engaged in milling production. The Borels had several steam mills, while the Kindsfaters had a water mill near the village of Popovka. In 1917, in the Popovskaya volost, out of 11 mills, only four remained with a water wheel. The mill in Konstantinovka was often referred to in documents as being located in the village of Popovka.

The milling complex in Konstantinovka includes buildings from different periods: the main four-story building dates back to the mid-1870s, while the brick structures are from the early 20th century. The mill operated until reconstruction, producing flour and animal feed, and workers were given bagels daily.
