The last Wednesday of every month is very special in Korea. Royal palaces and national museums are open for free and moviegoers and theatergoers enjoy discounts. Libraries across the nation open until late and major sports games including baseball and soccer offer discounts as well. This is the "Culture Day," an ambitious project of the Ministry of Culture, Sports and Tourism (MCST) to provide cultural welfare.
