Palacio Justo Arosemena, Parliament building in Calidonia, Panama

The Palacio Justo Arosemena is a parliament building in Calidonia composed of two main sections: a legislative chamber and an office tower connected by a horizontal administrative structure. This arrangement separates the spaces for debate and voting from daily administrative work while linking all operations through a unified complex.

The building was constructed between 1955 and 1956 during a period of national growth and modernization. It represented a shift to a permanent, purpose-built home for the legislature after decades of the parliament meeting in various temporary locations across the city.

The building is named after an important political figure from Panama's early independence period. Its design reflects mid-20th century modernist ideas that shaped how government buildings were constructed across Latin America.

The palace faces Plaza José Remón Cantera on Avenida Central, near Plaza 5 de Mayo. The plaza holds a bust of President Remón Cantera, placed so it looks toward the building. Approach from Avenida Central to see the two volumes and the connecting horizontal block together.

The building's design earned a distinction from the Miami Windows Corporation, which judged it one of the best of its kind; the windows that look like brise-soleils derive from Brazilian modernism. Across Avenida Central, the bust of José Remón Cantera faces the palace, intended to inspire legislators to pass laws benefiting the Panamanian people.
