The Van Gogh Museum is a museum located on Museum Square in Amsterdam. It is dedicated to Vincent Van Gogh and his contemporaries. The museum building is the work of Gerrit Rietveld, although the architect passed away a year after the project was awarded in 1963. It was completed only in 1973. In 1999 an exhibition wing designed by Japanese architect Kisho Kurokawa was added. The collection was created from Van Gogh's unsold works, which were inherited by his brother Theo after the artist's death, and half a year later by his widow Johanna van Gogh-Bonger. She passed the collection on to her son Vincent Willem van Gogh, who first lent it to the Stedelijk Museum in Amsterdam and later ceded it to the state-initiated Vincent Van Gogh Foundation.
