House of Pacific Relations in downtown San Diego's Balboa Park traces its founding to the 1935 California Pacific International Exposition, when 19 nations first occupied 15 cottages between the Ford Building and the Spreckels Organ Pavilion on Pan American Plaza. The complex now comprises 30 cottages representing 34 cultural groups — with the House of Somalia added in 2025 as the first African nation — each maintaining independent exhibition spaces for traditional costume, craft, and culinary displays alongside the artist studios at Spanish Village Art Center across the plaza. The Hall of Nations building anchors the complex as a shared venue for member nations without dedicated cottages, hosting rotating exhibitions and cultural programming on a schedule coordinated across all 34 participating groups. Sunday lawn programs from March through October stage live music, folk dance, and traditional food preparation on the grounds adjacent to San Diego Air & Space Museum on Pan American Plaza. Two anchor festivals — the annual Ethnic Food Fair and the International Christmas Festival during Balboa Park's December Nights — draw multi-day crowds for immersive culinary and performance programming spanning all 34 represented cultures.
