Castillo Azul

Castillo Azul is a two-story building on Ricardo Jimenez Oreamuno Boulevard featuring neocolonial and Mediterranean architectural details. The structure includes arches, balustrades, and columns, with six grand halls inside and decorative elements that span the interior and exterior spaces.

Built in 1911 by engineers Andreoli and Induni for Republican leader Máximo Fernández Alvarado, the building later served multiple official functions. It transitioned from a private residence to housing both the presidency and diplomatic operations before becoming a legislative assembly building.

The building displays European tastes through Italian granite floors and Andalusian mosaics that reflect early 20th century architectural preferences. These interior and exterior details show how international influences shaped Costa Rican design during that period.

The building now houses offices of Costa Rica's Legislative Assembly, situated between Central Avenue and 17th Street. Visitors should check for official events since access and timing can vary depending on legislative sessions and security protocols.

During a 1932 military uprising, a stray bullet damaged the building's distinctive blue tower while it functioned as the United States Embassy. This incident left marks on the structure and became part of the building's identity.
