A longtime destination for immigrants, Chicago is home to numerous ethnic museums worth a visit, including the Ukrainian National Museum (2249 W. Superior St.), the National Museum of Mexican Art (1852 W. 19th St.), and the Swedish American Museum (5211 N. Clark St.). But given the city’s massive Polish population, you may want to start with the Polish Museum of America ($10 for adults, $8.50 for seniors and students, open 11 a.m. to 4 p.m. on Tuesdays, Thursdays, and Saturdays), one of the largest ethnic museums in the country. Opened in 1935, it was founded to preserve historical pieces collected by the growing Polish diaspora. (Case in point: The 1939 World’s Fair in New York City featured a Polish Pavilion, with work by artists enjoying two decades of freedom after years of foreign rule, but after the Nazis invaded Poland later that year, ruling out returning the art to Europe, it found a home in Chicago.) These days, you’ll find plenty of treasures, including a massive stained glass window by Mieczysław Jurgielewicz; armor of the legendary 17th-century Winged Hussars; folk art; and an entire room dedicated to musician and statesman Ignacy Jan Paderewski, including the feather-shaped gold pen he used to sign the Treaty of Versailles. Some believe the pianist haunts the room. You won’t get that sort of eerily intimate experience among the masses at the Field Museum. 984 N. Milwaukee Ave., Noble Square
