The fountains of Neptune and Mermaid, known as the Mermaid, located in the Market Square, are the oldest fountains in Legnica. Neptune's Fountain is situated between the cathedral and the Old Town Hall. Originally, there was a water intake in this place, supplied from the municipal water supply, supplied from the water tower over the Młynówka. From 1588 there was a fountain here, the main element of which was the figure of the goddess Cerez. However, it did not survive the seventeenth-century fires of the city. The current Baroque Neptune Fountain has been in operation since 1731.
