The building owned by Oskar Schindler in a suburb of Krakow was crumbling and overrun by rats, The Telegraph reported Monday. Pressure from international groups and the local Jewish community spurred city officials to raise funds to restore the enamel and tinware factory.
The museum dedicated to Schindler is expected to open officially in December.
In addition to rooms and props featured in Spielberg's movie, the museum will have files on all the workers Schindler saved.
"This is one of the few places connected to the Holocaust which is not entirely negative and associated with dead bodies," project manager Aleksander Janicki told the newspaper.
A plaque outside the museum quotes a Jewish saying: "Whoever saves one life, saves the world entire."
Schindler died in poverty in 1974 and is buried in Israel.
