The Heidelberg Project is an outdoor art project in Detroit, Michigan. Specifically, it is in the McDougall-Hunt neighborhood on the city's east side, just north of the city's historically African-American Black Bottom area. It was created in 1986 by the artist Tyree Guyton, who was assisted by his wife, Karen, and grandfather Sam Mackey ("Grandpa Sam"). The Heidelberg Project is in part a political protest, as Tyree Guyton's childhood neighborhood began to deteriorate after the 1967 riots.
