Napoleon's Arch in Ślesin is a triumphal arch erected by the local residents between 1811 and 1812 as a tribute to Napoleon Bonaparte, in the hope that the emperor would pass through the area on his way east. The structure consists of a main semicircular arch and two lower pedestrian passages, adorned with pilasters featuring Ionic capitals, giving it a classicist character. At the top, there is a figure of the Napoleonic eagle, emphasizing its connection to the emperor and his military ambitions. From a historical perspective, the arch symbolizes the enthusiasm and hopes of the residents of Ślesin for Napoleon's triumph in the war against Russia, even though the emperor likely never visited the site. In 1972, the arch was damaged by a truck, but between 1976 and 1977, it underwent renovation and was adapted to the changing traffic layout in the area. Napoleon's Arch not only serves as a historical monument but also stands as an interesting site for tourists and locals, illustrating local cultural phenomena associated with the Napoleonic era.
