This gem of a gallery on the western edge of the Kirchberg plateau is as much an architectural landmark as it is a museum. The designs of architect I M Pei make this stunning edifice as eye-catching as the works of modern art on show within. The building is a mix of limestone and glass—the latter is formed into pyramids that both mimic the church spires of the old city across the Alzette valley, and echo Pei's similar work for the Louvre in Paris. Some of the many panoramic windows offer views onto the stone fortifications of Fort Thüngen, itself nearing the end of major restoration work. The museum's interior is light and airy and the perfect foil for the changing exhibitions by internationally renowned contemporary artists. There are no permanent displays, so repeat visits are always rewarding.
