The fountain was built in 1938 on the occasion of Benito Mussolini's visit to Trieste.
It was intended to be dismantled at the end of the celebrations for the event, but it survived, even if for long periods not working, the subsequent events.
At the beginning of the 1970s, functional restoration works were carried out without substantial changes compared to the original project. In a short time, the structure began to show water infiltrations in the underlying technical room and leaks from the hydraulic circuit, so the system fell into disuse again.
THE PROJECT
The project involves all the constituent parts of the structure, with the exception of the obelisk, which is only being restored in its stone cladding.
The goal of the intervention is to modify the structure in its aesthetic and functional characteristics, maintaining as much as possible, the overall image of the fountain, which over time has become a well-known visual landmark within the city.
A ring of jets in the external basin, which was not present in 1938, enhances the scenic impact. The water now not only falls from the obelisk, but "envelops" the viewer in a continuous circular motion.
Previously, the external part was static; with the new jets, even the water on the edge is in motion, creating reflections and plays of light (especially with the programmable LEDs).
These peripheral jets were designed with nozzles with adjustable orientation, so as to keep the water pattern consistent with the direction of the central waterfalls.
The external basin was completely redesigned, and the base was also modified, selecting stones compatible with the original Vrsar marble and carefully crafting the surface finishes to reproduce the historical effect.
The result is a seemingly subtle intervention, which is evident at night, when the fountain takes on a new visual dimension through LED lighting.
The following is a summary of the interventions completed in 2006:
- demolition of the flowerbed near the edge of the lower pool and partial reconstruction of the stone cladding;
- redesign of the basin of the larger pool with the creation of a semi-submerged internal concrete support to place new jet nozzles and the perimeter lighting system;
- structural consolidation and reconstruction of the bottom of the same pool to recreate the appropriate slopes and impermeability;
- reconstruction of the basins of the upper pools with the respective pipe crossings and water drains; - consolidation and partial reconstruction of the structures;
- renovation and additions to the hydraulic system with replacement of the vertical delivery nozzles located on the upper tanks and positioning of new jet nozzles along the external perimeter;
- complete replacement and modification of the lighting system with a system of computerized LED projectors (white and variable color lights);
- cleaning and restoration of the stone parts of the obelisk and the external edge.
For night-time lighting, 60 25 W units were installed to illuminate the tanks and 25 6 W white LED projectors on the bottom of the lower tank, all integrated into the modified structure and controlled, for the switching on and color sequence, by the systems located in the underground compartment.
