Entering the City trough the western entrance. you begin the sightseeing with a large polygonal fountain with 16 stone-carved maskerons out of which the water runs. The fountain was designed by Onofrio della Cava from Naples, who also designed another small fountain at the other end of Placa. The fountains were built for public use on the occasion of the completion of the City water supply in 1438, when the spring water was brought from Rijeka Dubrovačka, situated 12 kilometres away. The old water supply is today connected with the new waterworks system. The cupola of the monumental Onofrios Fountain was damaged in the earthquake of 1667, and later reconstructions failed to restore its original form.
