Northerly Island

Northerly Island is a man-made peninsula along Chicago's lakefront. 
The site of the Adler Planetarium, Northerly Island connects to the mainland through a narrow isthmus along Solidarity Drive made-up by Neoclassical sculptures of Kościuszko, Havliček and Copernicus. With the demolition of Meigs Field Airport, it is now a part of the Museum Campus and has been made into parkland. 
A semi-temporary concert venue, the Huntington Bank Pavilion occupies part of the site of the former airport.
