Sculptor Bernhard Luginbühl, one of Switzerland's most famous artists, opened his garden to the public in 2000. Visitors can see many of his best-known sculptures. Fifty-nine pieces are exhibited in the Mötschwil sculpture park near Bern. Almost as intriguing as these sculptures are the enormous quantities of scrap metal on display - including 150 ploughs, an entire airplane wing, and piles of rusty chain. These were the bones of future sculptures. Hans Christoph von Tavel, former director of Bern's fine arts museum, once described Luginbühl's work as a "constant battle against chaos" and in the park that process of transforming junk into sculpture is partially revealed. Even the garden's concrete walkway, patterned with inlaid wrenches, keys, horseshoes and other bits of scrap iron, is a work of art. Following this walkway, visitors encounter colossal pieces such as "Atlas" with its moving ball, which stood in front of Berlin's National Gallery during Luginbühl's one-man show there in 1972. Less well known, but no less fascinating, are his "portraits" of a butcher and a forester assembled from knives and saws. These two statues, and the materials they are made of, show why Luginbühl scholar, Jochen Hesse, calls the sculptor "an archaeologist of work". The sculpture garden surrounds the house where the Luginbühls have lived since the 1960s. The artworks are Luginbühl's gift to the trust he set up in 1998 to ensure that his work would always be shown as he wished. "My family and I made the whole park ourselves. We put the sculptures just where I want them to be." Luginbühl was born in Bern in 1929, the only son in a family of butchers. Although he worked in the slaughterhouse as a youngster, his family allowed him to be apprenticed to a gravestone maker. He was also accepted into Bern's School of Applied Arts. At 19 he exhibited his first sculpture - in stone - at Bern's Kunsthalle. It wasn't long before he turned from stone to iron, first forging pieces himself and then assembling them from junk. By 27 he was exhibiting at the Venice Biennale. In 1963 he had a one-man show in New York, and four years later his work was displayed at the Montreal World's Fair. One of the first things visitors to Switzerland see is a Luginbühl sculpture - his work "Sisyphus" is in Terminal B of Zurich's Kloten airport. But his sculptures can also be found all over the world, from Tokyo to Tel Aviv.
