Polonia Triangle (Polish: Trójkąt Polonijny), or the Polish Triangle, is a plaza located in West Town, in what had been the historical Polish Downtown area of Chicago. A single-tiered fountain made of black iron with a bowl about nine feet in diameter is installed at its center. Polonia Triangle derives its name from the Polish word Polonia ("Polish diaspora"), which itself comes from the Latin name for Poland. Polonia Triangle was considered to be the center or town square of Chicago's Polish Downtown, the city's oldest and most prominent Polish settlement. In many ways it functioned as the capital of American Polonia, with the headquarters for almost every major Polish organization in the United States clustered in its vicinity.
