(CNA, Warsaw, May 17, by reporter Cheng Ching-yu) The 22nd Warsaw "Night of Museums" concluded late on the night of the 16th, attracting over 320,000 citizens and tourists to the streets. From major museums and art galleries to normally heavily guarded government institutions, all revealed their mysterious veils after dusk, filling Warsaw with artistic romance and the vibrant energy of exploring the dark from evening until late at night. According to the event's official website, Warsaw's "Night of Museums" (Noc Muzeów), established in 2004, attracted over 324,000 citizens and out-of-town visitors to the streets through the incentives of being "night-exclusive" and "completely free," complemented by the entirely free "Special Museum Bus Lines" (Specjalne linie muzealne). One of the highlights of the "Night of Museums" was the limited-time opening of the core of national power and various government departments. Normally closed to the public, the Polish Presidential Palace (Belweder), the Chancellery of the Prime Minister, the Ministry of Finance and National Tax Administration, the Ministry of Education, the Ministry of Justice, and the Ministry of Health were all exceptionally opened for public visits. This year, a total of 331 venues in Warsaw were open for free at night. Major museums and art galleries also launched a series of lectures, workshops, performances, and other rich cultural activities, among which the historic Royal Łazienki Park became a popular romantic spot. The Old Orangery (Stara Oranżeria) in Łazienki Park hosted a late-night concert by the Polish Royal Opera (Polska Opera Królewska), while the Amphitheatre (Amfiteatr) in the park featured a mime performance titled "The Magic of One Night" (Czar jednej nocy). Visitors could also admire murals themed on the four seasons and birds in the White House (Biały Dom) in the Royal Park, and learn traditional Polish court dances to live music at the Palace on the Isle (Pałac na Wyspie).
