The house in Amsterdam that hid Jewish teen-ager Anne Frank during World War II officially unveiled its new look Tuesday after 10 years of renovation.
Queen Beatrix and Prince Claus of the Netherlands, former German President Richard von Weizsaecker and Miep Gies, the woman who helped Anne and seven others hide, attended the opening.
Anne wrote her famous diary while she, her family and four other Jews lived hidden from the Nazi occupiers in the cramped back rooms of the narrow house on the Prinsengracht canal until they were betrayed and arrested in August 1944.
But this renovation -- which was carried out without closing the museum -- has focused on the rest of the building.
It fulfills Anne's father's wish that the front of the house, which contained his spice and jam trading company, should be restored to its original state.
Otto Frank was the only one of the eight to survive the war and died in 1980.
Using photographs, the original floor plan and Miep Gies's memory, the Anne Frank Foundation has re-created the atmosphere of the office as it was in the 1940s -- including the smell of spices.
Although Anne and the others spent the bulk of their time in the annex, the front chambers also played a part in Anne's life, said Hans Westra, director of the foundation.
"We hope visitors will get disoriented when wandering through the front part. They must get the feeling that somewhere there are hidden chambers," he said. Previously, visitors used to be able to walk straight into the secret annex.
The annex itself remains almost totally empty, just as it was just after the Franks' arrest and deportation, because the Nazis took away the furniture. Only the bookcase that hid the doorway remains.
But specialists have been drafted to preserve the fading pictures and postcards of film stars that Anne pasted to her bedroom wall.
"Behind some of the pictures we found other pictures, which Anne probably thought too childish after a while," one of the experts said.
The house itself now contains information about Anne's experiences in the Bergen-Belsen concentration camp, where she died of typhus weeks before it was liberated. A new building next door provides information on the Holocaust in general.
A visitors' cafe and a virtual tour through the house on computer also have been added.
The increase in space makes it easier to accommodate the huge numbers of visitors. There were 822,000 last year.
