Mokrosęk is a village located in the Masovian Voivodeship, within the Radom County, and is administratively part of the Jedlińsk municipality. It is known for its rich history, dating back to medieval times, when it was first mentioned in court records in 1411 as Mocrossank. The etymology of its name may indicate a marshy area or even former inhabitants associated with forested regions, linked to the Radom Wilderness. Architecturally, the village once had a manor with a brick building, the remains of which survived until the 1980s. Today, Mokrosęk benefits from modernized infrastructure, including electricity, water supply, and roads, which provide easy access to nearby towns. Culturally, Mokrosęk stands out for its musical traditions, particularly in the realm of folk art, with recordings of local violinists such as Edward Sulowski and Piotr Pająk. The village was an important center during World War II, where local structures of the ZWZ-AK (Union of Armed Struggle-Home Army) operated, and later, local anti-communist underground units. Notable historical events in Mokrosęk include the Battle of Jedlińsko-Jankowice in 1809. In 1916, a one-class primary school was established here, and after World War II, a kindergarten was also created. The residents of Mokrosęk place great importance on their cultural heritage, as seen in local initiatives and community activities. Currently, the village has about 230 inhabitants and remains active in local politics and cultural initiatives.
