National Palace, Government building in San Salvador, El Salvador

The National Palace is a two-storey building in San Salvador's historic centre, predominantly Neoclassical with some Renaissance and, to a lesser degree, Gothic decoration; its bronze and iron gates and ornaments are Art Nouveau. Engineer José Emilio Alcaine built it between 1905 and 1911 under foreman Pascasio González Erazo, using materials imported from Germany, Italy and Belgium. It has four main rooms and 101 secondary rooms.

Built between 1905 and 1911, the palace replaced an earlier structure destroyed by fire in 1889. Its construction was funded through taxes on coffee exports, which were vital to the country's economy at that time.

The Blue Room, with Ionian, Corinthian and Roman elements, housed the Legislature from 1906 and is now called the Salvadoran Parliament; it was declared a National Historic Landmark in 1974. The Red Room has served ceremonial purposes since the administration of General Maximiliano Hernández Martínez, and the Pink Room held the Supreme Court before becoming the Ministry of Defense.

The palace faces the Plaza Libertad in the historic centre of San Salvador; its bronze and iron gates and Art Nouveau ornamentation are visible from the square. The building belongs to the Ministry of Culture, and until 2023 it housed the General Archive of the Nation, later moved to the BINAES. The four main halls are named for their colours.

The Blue Room, now called the Salvadoran Parliament, was the meeting place of the Legislature from 1906 and was declared a National Historic Landmark in 1974. Its classical architecture mixes Ionian, Corinthian and Roman elements, and the room keeps the name of its former purpose.
