Serpent Tree, Sculpture in the courtyard of the Musée des beaux-arts, Angers, France

L'Arbre-serpents is a 1992 polychrome sculpture by Niki de Saint Phalle in polyester resin, installed in the courtyard of the Musée des beaux-arts d'Angers since 2005. It was restored by Gérard Haligon, the artist's historical sculpture publisher, with funding from the Fondation BNP Paribas, which brought back its original polychromy and made it more resistant.

Created by Niki de Saint Phalle in 1992, the sculpture first stood in the garden of her son before the Angers museum acquired it and installed it in its courtyard in 2005. A 1999 copy is in the Missouri Botanical Garden and the National Museum of Women in the Arts in Washington. Degradation appeared in 2010; it was boxed from 2012 and removed from the terrace in late 2016 for restoration by Gérard Haligon, funded by the Fondation BNP Paribas.

The work is one of several versions Niki de Saint Phalle made of the motif; a copy dated 1999 is displayed in the Missouri Botanical Garden and at the National Museum of Women in the Arts in Washington. The Angers piece was first placed in the garden of the artist's son before the museum acquired it and installed it in its courtyard in 2005.

The sculpture stands in the courtyard of the Musée des Beaux-Arts d'Angers, where it was installed in 2005. It was removed from the terrace at the end of 2016 for restoration in a specialised workshop, after being hidden behind a protective casing since 2012. Visitors should check with the museum whether the work is back on public view.

A copy made in 1999 stands in the Missouri Botanical Garden and another is held by the National Museum of Women in the Arts in Washington. The Angers piece was first placed in the garden of the artist's son before the museum acquired it and installed it in its courtyard in 2005.
