San Salvador is rich in Spanish heritage, and its historical center contains architecture of a kind not found elsewhere in Latin America. The Metropolitan Cathedral was built in the 1950s combining Baroque and eclectic styles of architecture. The National palace, built in 1905, is a mix of Gothic, Neoclassical, and Renaissance Revival architecture. The National Theater is the oldest theater in Central America, being built in 1917 in the French Renaissance Revival style with details in the Rococo, Romantic and Art Nouveau architectural styles. The building contains three levels of seats, including a Presidential box at the center of the second level, and has seating for 650 people. The structure is surmounted by an ellipsoidal dome, the interior of which is adorned with a mural painted by Carlos Cañas and a crystal chandelier.
