Zalewo, formerly known as Zełwałd, is a town in the Warmian-Masurian Voivodeship, situated on Lake Ewingi. It was granted town rights in 1305 by the Teutonic Knights and served as the seat of a county for over 200 years. After World War II, due to wartime destruction, the town lost its municipal rights, which it only regained in 1987. Zalewo covers an area of 8.22 km² and had a population of 2,165 in 2018. The town is located in the historic region of Pomesania and Upper Prussia, which significantly influenced its history and development.
The high-quality architecture of Zalewo is represented by the Gothic Church of St. John the Apostle from the 14th century, as well as preserved fragments of the town walls and towers. Other historical monuments include 19th-century houses and a Jewish cemetery, reflecting the diverse cultural heritage of the region. A notable event in the town's history was the discovery of a coin treasure in 1991, which inspired the writing of a novel.
Zalewo is also a commercial and service center with developed industries, including timber and metallurgy. After World War II, the town was 70% destroyed, but it was rebuilt and developed over time. In 2013, the modern Ekomarina sailing harbor was opened. The town engages in international cooperation, with partnerships in Saalfeld and Rudziskes.
Religious life is represented by the Parish of St. John the Apostle. The cultural heritage is showcased during events such as the Museum Night, while sports are promoted through local football and sailing clubs. With a rich history dating back to the Middle Ages and influenced by both German and Polish cultures, Zalewo is a place full of adventure and discoveries for tourists and residents alike.
