As a building by Mies van der Rohe nears completion in Indiana, we explore five buildings by renowned 20th-century architects such as Le Corbusier and Frank Lloyd Wright that weren't built until years after they died.

Baghdad Gymnasium in Baghdad, Iraq, by Le Corbusier
When French architect Le Corbusier, one of the 20th-century's most influential architects, died in 1965 he left behind the plans for a concrete sports centre for the Iraqi capital.
Originally commissioned in 1956 by King Faisal II for the 1960 Summer Olympics, plans were derailed by the 1958 military coup that overthrew the monarchy. Construction on the project began in 1978 under president Saddam Hussein and the sports complex with its 3,000-seat stadium opened in 1980, 15 years after Le Corbusier's passing.

Four Freedoms Park in New York, USA, by Louis Kahn
American architect Louis Kahn designed a park to commemorate US president Franklin D. Roosevelt in 1974, but it didn't open to the public until 2012 ? almost 40 years after Kahn's death.
Kahn, known for his brutalist style, died the same year shortly after designing the park, which languished for decades due to funding issues. Located at the southern tip of Roosevelt Island, the triangular park features rows of trees and a granite monument framing a bust of Roosevelt.
