This classic capitol in the heart of San Juan is home to the Legislative Assembly, House of Representatives, the Senate and a whole lot of Puerto Rican history. Visitors to this regal site, which officially opened in 1907, will find massive marble columns, ornate stonework and a brightly colored capitol dome, in addition to the Architecture and Construction Archives of the University of Puerto Rico. These include rare ink and cloth sketches, as well as the original 38 blue print plans for the structure. Visitors say this classic building is a major departure from the rest of the old city, but a few hours wandering the halls, learning about Puerto Rican history and politics is a worthy addition to any San Juan visit.
