The Chopin Museum occupies the 17th-century Pałac Ostrogskich, which towers above Tamka. The best approach is via the steps from Tamka. In the 19th century the Warsaw Conservatory was housed here (Ignacy Paderewski was one of its students). In 2010, on the occasion of Chopin's Year celebrations, a modest collection of mementos, including the last piano played by the composer, was turned into an exciting, interactive, state-of-the-art display across four floors of the Palace. Many programs and events are running here throughout the year, including piano recitals and museum lessons for children. The museum's motto is for the visitor to "Experience Chopin." The works of Chopin (1810–49) took their roots from folk rhythms and melodies of exclusively Polish invention. Thanks to this composer, Poland can fairly claim to have been the fountainhead of popular music in Europe in the mid-19th century, when the Chopin's polonaises and mazurkas whirled their way around the continent.
