America's Courtyard, Stone sculpture at Adler Planetarium, Chicago, United States.

America's Courtyard is an outdoor stone sculpture by Brazilian artists Ary Perez and Denise Milan, installed outside the Adler Planetarium in Chicago. The work, subtitled A Symbolic Integration of the Americas, is made of stone blocks arranged as a courtyard.

The sculpture was first installed near the Art Institute of Chicago before being moved to its current location south of Adler Planetarium in December 2000. This relocation established it as a permanent part of the waterfront landscape.

Brazilian artists Denise Milan and Ary Perez designed this outdoor work to express the link between the continents north and south of the equator. The arrangement of stones conveys this connection to those who walk through the space.

The work remains open to visitors throughout the year at no charge as part of Chicago's public art collection. You can approach it from multiple sides and view it from different heights as you walk around.

The work is credited to the Brazilian husband-and-wife artists Ary Perez and Denise Milan, not to an astronomer, despite its setting beside the Adler Planetarium. Their title, America's Courtyard: A Symbolic Integration of the Americas, states the theme: unity across the hemisphere.
