Mirabell Palace is a historical building in Salzburg, Austria. It was originally built in 1606 by Prince-Archbishop Wolf Dietrich von Raitenau for his mistress Salome Alt. In the early 18th century, it was renovated and expanded by Prince-Archbishop Franz Anton von Harrach and his successor, Prince-Archbishop Johann Ernst von Thun.

The palace has a beautiful Baroque style with a large garden in the rear. The garden is divided into several sections, including the Pegasus Fountain, the Dwarf Garden, and the Hedge Theater. It is considered one of the most beautiful gardens in Salzburg and is a popular destination for visitors.

Inside the palace, there are several rooms that are open to the public, including the Marble Hall, the Tapestry Room, and the Angel Staircase. The Marble Hall is one of the most famous rooms in the palace and is often used for weddings and concerts. The Tapestry Room features tapestries from the 17th century, and the Angel Staircase has impressive frescoes on its walls and ceiling.

Mirabell Palace has been used as a filming location for several movies and television shows, including The Sound of Music, which featured the famous scene of Maria and the von Trapp children singing "Do-Re-Mi" on the steps of the palace. Today, it is a popular tourist attraction and a venue for cultural events.
