Otwock County, located in the Masovian Voivodeship, was reestablished in 1999 as a result of administrative reform. Its seat is the town of Otwock, which for many years retained its spa character, influencing the region's architecture. The county includes urban municipalities (Józefów, Otwock), urban-rural municipalities (Karczew, Osieck), and rural municipalities (Celestynów, Kołbiel, Sobienie-Jeziory, Wiązowna).
The historic architecture of Otwock, including wooden villas from the late 19th and early 20th centuries, attracts tourists. The largest municipalities in the county by population are Otwock and Józefów, which are developing dynamically while preserving local folklore. Otwock County also boasts cultural traditions linked to its multicultural heritage, including numerous artistic events and festivals.
The county was originally established on January 1, 1958, and underwent numerous administrative reorganizations. Historically, Otwock was significant as a health resort, and some of its districts, such as Celestynów and Wiązowna, gained recognition for their health benefits. In 1975, the county's territory was incorporated into the newly created Warsaw Capital Voivodeship, which altered its administrative structure and borders.
An interesting fact is that in the 1990s, authorities restored the status of urban-rural municipalities, and some towns gained prominence, such as Karczew, which regained its town rights in 1959. Additionally, parts of Otwock County were separated and became part of the Halinów municipality in Mińsk County, which also influenced the county's current shape. It is also worth noting that Otwock County has many green areas, forests, and nature reserves, which support outdoor activities and recreation for both residents and tourists.
The county borders Warsaw and the counties of Piaseczno, Mińsk, Garwolin, and Grójec, making it an attractive region for those seeking contact with nature while being close to the capital. Efforts to preserve and promote the culture and architecture of this area are an important part of local and community development policies in Otwock County.
