Once a place of gathering and meditation for the monks of Santa Cruz, Jardim da Sereia, as it is known in Coimbra, is currently one of the great green spaces in the city, located next to Praça da República. Its designation is due to the identification of the existing sculpture at Fonte da Nogueira, which represents a Triton opening its mouth to a dolphin from which the water gushes into a shell, with the figure of a Mermaid.
