A popular facility of Luxembourg is the Philharmonie Luxembourg. Also known as the Grand-Duchesse Josephine-Charlotte Concert Hall, the Philharmonie is situated in the Kirchber quarter on the north-east side of Luxembourg. The Luxembourg Philharmonic Orchestra, the nation's orchestra, is the primary tenant of the Philharmonie. The Philharmonie Luxembourg project began in 1995 under the supervision of the Luxembourgian government. It is one of several public attractions built in recent years. The building was inaugurated on June 26, 2005. Five months prior to the hall's opening, the Grand Duchess Josephine-Charlotte, for whom the facility is named after, died on Jan. 10, 2005. The extravagant curves of the building make it an ideal location for musical events. Perfect architectural conditions in the building's three concert halls welcome orchestras, solo recitals, and jazz concerts. Grand Auditorium Combining the proven acoustics of shoe-box concert halls, the Grand Auditorium boasts the qualities of a Shakespearean state. The hall features eight lateral towers and an orchestra pit. Seating can accommodate up to 1,500 spectators. The Salle de Musique de Chambre Bordered by elegant curved walls, the Salle de Musique de Chambre can house up to 300 visitors. The chamber is bordered by curved walls that reflect sound above the stage. Espace Decouverte Considered the most flexible and intimate of the concert halls is the Espace Decouverte. The hall seats up to 120 guests. Interactive workshops for children are often hosted in the hall which also shows film, video, and art exhibitions. The building itself features a unique oval shape as designed by French Pritzker Prize winner Christian de Portzamparc. The design was made possible through the use of colonnade screen constructed by more than 823 steel columns. Inside, along with its auditoriums, the Philharmonie features a concert organ. Built and installed by Karl Schuke Berliner Orgelbauwerkstatt, the organ features four manuals, 2.5 octave pedal-boards, 81 registers, and 6738 pipes. Luxembourg's Ministry for Public Works owns the building. Today, the general public can partake in a guided tour free of charge. Tours take place at 10:30 a.m. on Saturdays. Registration is required. The facility is also available for private rental to host an array of events. Overall, activities at the Philharmonie Luxembourg boast a large spectrum of musical interests.
