« The abolition of slavery in Costa Rica was an act of justice and humanity that preceded many American nations. »— Juan Mora Fernández, Head of State, Decree of Abolition of Slavery, 1824
Your journey begins in front of the Teatro Nacional de Costa Rica, a 35-meter-high European Neo-Renaissance building, constructed between 1891 and 1897 and inaugurated on October 21, 1897. This monument, designed by Manuel Gómez Minakata, is an architectural testament to the prosperity of Costa Rica's coffee era, funded by a tax on coffee exports. The Corinthian columns of its stone facade still bear the original white marble inscription 'A la nación,' recalling the young republic's commitment to culture and education after the abolition of slavery in 1824, a major landmark in the history of San José Centro.
A short walk away, the Plaza de la Cultura, laid out in 1977 on the site of a 19th-century market, invites reflection on San José's cultural continuity. Adjacent, the Melico Salazar Theater, built in 1928, offers renowned excellent acoustics. The Museo del Oro Precolombino, located beneath the square, houses artifacts dating from 500 BC to 1500 AD, highlighting Costa Rica's ancestral heritage. This site symbolizes the evolution of Costa Rican society, from its pre-Columbian roots to modernity, including institutional reforms led by figures like Manuel Aguilar Chacón.
Parque Central, or Plaza de la Constitución, established in 1858 as the civic heart of San José, is your next stop. Its central kiosk, in Victorian style with a metal structure, was built in 1881. The 'Fuente de la Yunta,' the central fountain, is a powerful symbol of agricultural labor and the abolition of servile work. This 4-hectare park, with its centuries-old trees dating back over 150 years, is a historic gathering place that has seen political figures like Braulio Carrillo Colina, working on the independent Costa Rica's legal reforms, and marks the center of San José's heritage.
Your exploration then leads you to the Edificio Metálico, an entirely wrought-iron structure imported from Belgium in 1890 to serve as a primary school. Weighing approximately 150 tons and measuring 45 meters long by 25 meters deep, this building is an architectural testament to Costa Rican technological progress and the coffee era. Now a museum, it preserves artifacts from the colonial period and the abolition, offering insight into the social and economic transformations that followed the 1824 decree, and completing the thematic circuit of San José Centro.
Finally, the Museo Nacional de Costa Rica, located in the former Fortaleza Bellavista, marks the end of your immersion in San José's history. This military fort, built in 1870 with 2-meter-thick stone walls and 8-meter-high corner towers, was transformed into a museum in 1950. It houses collections on slavery and its abolition in 1824, including original documents such as decrees and 19th-century correspondence. The museum's archaeological garden displays pre-Columbian and colonial artifacts, completing this historical walk and reinforcing the motto "Por siempre libres" that has guided Costa Rica since the abolition of slavery.
