Brok is a town in Poland, located in the Masovian Voivodeship, Ostrów County, with a rich history dating back to 1203. The local settlement on the trade route connecting Pomerania with Kievan Rus was granted town rights by Płock Bishop Wincenty Przerębski in 1501. The town developed intensively in the 16th and 17th centuries as an important port on the Bug River and a commercial center, until its destruction during the Swedish invasion in 1657. In the 19th century, Brok became a clerical town and gained significance through the development of the local community and the activities of local institutions, including the Forest-Practical Institute. After numerous upheavals, the town regained its municipal rights in 1922, when residents undertook efforts to modernize it and turn it into a resort, contributing to the development of tourism and culture. Brok is home to several historical monuments, such as the beautiful Gothic-Renaissance Church of St. Andrew the Apostle, the ruins of the bishops' castle, a Jewish cemetery, and a classicist town hall, all testifying to the town's rich history. Important to the memory of the inhabitants are memorial sites, such as the restored cemetery by the river, where soldiers who died during World War I are buried, and a burial mound from the time of the plague epidemic. Brok, situated in the Lower Bug Valley, is intersected by national and regional roads, with the nearest PKP railway station located in Prostynia. The town went through difficult times after World War II, but it was not until the late 1950s that it began to develop more dynamically. An interesting fact is that in the 1930s, Brok was home to Polish physician and Minister of Public Health Tomasz Janiszewski. Today, despite economic changes, the town remains a place with a rich history, vibrant heritage, and tourism potential.
