El Capitolio
The marble-domed capitol on Puerta de Tierra in San Juan, holding the island's constitution under the rotunda.
Updated 2 September 2026
El Capitolio was built between 1925 and 1929 in white Georgia marble on the neck of land between Old San Juan and the rest of the city, a domed neoclassical building housing the island's legislature. Under the rotunda, mosaics and murals cover the history of Puerto Rico, and the original 1952 constitution is displayed there. Guided tours go through the rotunda and the chambers when the legislature is not sitting.
