Museu Obert de Geologia. Roques al Carrer

About this museum

Barcelona's Museu Obert de Geologia transforms city streets into an expansive geological exhibit, displaying natural rock specimens embedded directly in urban landscapes. Visitors can explore diverse stone types and formations without entering a traditional museum space, with free access allowing spontaneous geological discovery. Each carefully placed rock tells a story of Earth's complex formation, inviting passersby to examine geological structures hidden in plain sight throughout the city's thoroughfares.
