Water has always been the lifeline of civilizations, shaping cities and their growth. The Republic of Dubrovnik, a powerful maritime state, was no exception. However, Dubrovnik’s strategic position along the Adriatic came with a major challenge—freshwater scarcity. For centuries, the city relied on wells and cisterns, but as its population grew, these sources became insufficient. The breakthrough came in the 15th century when Onofrio Della Cava, an innovative Italian architect, introduced an advanced water supply system. His work, particularly the Onofrio’s Fountain, transformed the city, ensuring its prosperity and sustainability.
Water Supply Challenges in the Republic of Dubrovnik
Despite its wealth and influence, the Republic of Dubrovnik struggled with one of the most basic necessities—freshwater. Unlike other medieval cities with abundant rivers, Dubrovnik’s geographical position made it reliant on rainfall and underground reservoirs. Before Onofrio’s intervention, the city’s residents depended on manually collecting water from scattered wells and cisterns, which were often insufficient during dry seasons.
Public health was another growing concern. Limited water access meant inadequate sanitation, increasing the risk of diseases. This problem was further exacerbated during sieges when water supplies were cut off, making the city vulnerable. As Dubrovnik expanded, so did its need for a sustainable water infrastructure.
Onofrio Della Cava’s Fountain: A Revolutionary Feat of Engineering
The turning point came in 1438 when the Republic commissioned Onofrio Della Cava to design a system that would provide the city with a steady water supply. His solution? A sophisticated aqueduct that transported water from the Dubrovnik River, located 12 kilometres away, directly to the city.
At the heart of this system was Onofrio’s Large Fountain, a monumental structure built near Pile Gate. This 16-sided masterpiece featured intricately carved stone masks, each acting as a spout to distribute water to the citizens. More than just a water source, the fountain became a gathering spot, reinforcing the sense of community among Dubrovnik’s inhabitants.
For those exploring Dubrovnik today, Onofrio’s Fountain remains a must-visit historical landmark. If you’re planning a visit, check out this guide for more details on Dubrovnik’s top attractions.
Before Onofrio: Water Scarcity and Its Impact
Life in Dubrovnik before Onofrio’s system was challenging. With no direct water source, the Republic’s residents relied on rainfall collected in private and public cisterns. These were often inadequate, and during dry periods, water shortages became a serious issue. The lack of a proper distribution system also meant that water access was unequal, favoring wealthier citizens with larger cisterns.
Beyond daily inconveniences, this scarcity hindered economic activities. Agricultural production was limited, and trade—one of the Republic’s main economic drivers—suffered, as visiting ships struggled to replenish their water supplies. The Republic needed a long-term solution to maintain its prosperity.
After Onofrio: A Transformed Dubrovnik
With the completion of the Onofrio aqueduct and fountain system, Dubrovnik entered a new era of urban development. Freshwater was now accessible throughout the city, improving sanitation and public health. The presence of a reliable water source also meant greater economic expansion, as merchants and sailors could depend on Dubrovnik as a vital resupply point.
Onofrio’s Fountain also played a key role in social life. It became a central meeting point where citizens gathered not only to collect water but also to exchange news and strengthen community ties. Even today, the fountain continues to be a symbol of the city’s ingenuity and resilience.

The Legacy of Onofrio Della Cava’s Water System
The impact of Onofrio’s water system is still evident today. While Dubrovnik now has a modern water infrastructure, traces of the original aqueducts remain, offering a glimpse into the city’s innovative past. The Large Onofrio’s Fountain near Pile Gate and the Small Onofrio’s Fountain in Luža Square continue to provide fresh drinking water to visitors—a testament to the durability of medieval engineering.
Onofrio’s work set a precedent for sustainable water management, a lesson that remains relevant today. As modern cities face water scarcity and climate challenges, Dubrovnik’s historical system serves as a reminder of the importance of thoughtful, long-term urban planning.
