Traditional Thai art, long developed within religious and royal contexts, continues to be sponsored by various government agencies in Bangkok, including the Department of Fine Arts' Office of Traditional Arts. The SUPPORT Foundation in Chitralada Palace sponsors traditional and folk handicrafts. Various communities throughout the city still practice their traditional crafts, including the production of ''khon'' masks, alms bowls, and classical musical instruments. The National Gallery hosts permanent collection of traditional and modern art, with temporary contemporary exhibits. Bangkok's contemporary art scene has slowly grown from relative obscurity into the public sphere over the past two decades. Private galleries gradually emerged to provide exposure for new artists, including the Patravadi Theatre and H Gallery. The centrally located Bangkok Art and Culture Centre, opened in 2008 following a fifteen-year lobbying campaign, is now the largest public exhibition space in the city. There are also many other art galleries and museums, including the privately owned Museum of Contemporary Art.
