Fans of The Sound of the Music won't be able to stay at the Trapp family villa in Austria now that Salzburg has blocked a plan to turn it into a hotel. Mozart's home town has effectively blocked the proposed deal. The developers plan to appeal.

An astonishing 40% of overnight stays in Salzburg are booked by Sound of Music fans. But neighbors protested that the hotel plan would disrupt the community. The von Trapps lived in the palatial home from 1923 until they fled the Nazis in 1938.

The 1965 film is based on the true story of how trainee nun Maria wins over Baron von Trapp and his seven children through her singing and good nature, and its fame draws hundreds of thousands of tourists to Salzburg, and the villa, each year.

But Salzburg's planning council is standing in the way of the hotel project because residents are worried the city, close to Austria's idyllic Alps, will be overrun by more tourists, according to the Villa Trapp company.

"Salzburg bites the hand that feeds its tourism," the developer said in a statement on Wednesday.

"It could be thought madness that a new tourism venture is being blocked when global financial problems could result in far fewer tourists for Salzburg," it said.

No one from the local government was available for comment.

The hit movie, which starred Julie Andrews and Christopher Plummer, has inspired musicals worldwide and healthy sales of Sound of Music merchandise.

In Austria, visitors can get married at the villa, which was home to the real von Trapps before they fled the Nazi takeover of Austria.

Nazi Germany's security chief Heinrich Himmler used the villa, just outside Salzburg, as a home close to the Austrian Alps until 1945. Some opponents of the hotel have accused the developers of wanting to build a memorial to Nazism.

The developers want to provide 14 hotel rooms for guests to the villa and say they have a solution to the traffic problems which extra tourists could cause. They are looking to appeal the decision but the whole process could take up to three years.
