The Palace Museum, also known as the Forbidden City, will be closed to the public every Monday afternoon for renovation and maintenance, it announced Monday. The museum launched a pilot plan to close every Monday afternoon from Jan. 1 to March 31, 2013.

The official half-day opening will start on April 1, except public holidays and Mondays during the summer months of July and August.
