Auditorio y Palacio de Congresos El Batel

El Batel is Cartagena's striking centerpiece for arts and culture, a sleek glass-and-steel building sitting right on the harbour waterfront. It hosts everything from classical concerts and opera to international congresses, making it one of the most versatile venues on the Spanish Mediterranean coast. If you're looking for a quality night out, check the programme — the lineup regularly punches well above what you'd expect for a city this size.
