The Grand Theatre de la ville de Luxenbourg was built in the 1960s to mark the millennium of Luxembourg. Opening on April 15, 1964, the theatre is a state-of-the-art building that was designed by Parisian architect Alain Bourbonnais. Since its original construction, the facility has been renovated to better serve the needs of its patrons. The structure features building materials from Austria, Switzerland, Germany, France, Belgium, the Netherlands, and Luxembourg. Today, the Grand Theatre de la ville de Luxenbourg, which is referred to by locals as the New Theatre, has hosted major concert artists from across the world. The theater has also welcomed local artists and serves as a venue for ballet, modern dance, opera, and drama featured in numerous languages. Notable festivals and theatre groups hosted at the theatre include "La Monnaie de Bruxelles", the "Nederlandse Opera d'Amsterdam", the "Wiener Festwochen" and the Festival of Aix-en-Provence. The facility has two showrooms. The main room seats 943 guests and boasts a vast variety of sophisticated, high-tech state sets. The second auditorium seats 400 guests. The exterior of the theatre is just as exquisite as its interior. The exterior sight alone is enough reason to visit the Luxembourg's popular attractions.
