A competition entry for a museum to be located in the former cistern called Piscina Mirabilis, territorial-scale wise the proposal seeks to establish an ‘archaeological route’ connecting landmarks of the Roman Empire vestiges in the Bacoli region, where the new museum would play a key role by maximizing the cultural value and identity of the entire region, the city of Bacoli and the other monuments they encompass.



Cesare Brandi (1963) has suggested that to intervene in a ruin one should not go back to what it once was or looked like. Brandi’s principle of distinguishability guides our design, which reassures the monument’s unique architectural features while adding new elements to generate a spatial setting for viewing contemporary art.



The series of voids resulting from the poche of the cruciform pillars supporting the cistern’s vaulted structure becomes a design force: a new floating path resembling the Augustan aqueduct, from Miseno to Serino, is placed in between the prominent piers, now immersed into a reflective pool. What once stored 12,600 m3 (3.3M gal) of water now gives room to art and movement, transforming the former voids into what Louis Kahn has called a ‘society of spaces’.



The ticket counter leads to a glass bridge above the former NW staircase, which is connected to a cantilevered platform over steel structure, where the reception desk and elevator are located. This suspended lobby is visually integrated to the street through the glass in-filled arched openings, unfolding into a staircase that allows visitors to start immersing in the space below. Upon descending, visitors are directed towards the high-ceiling atrium below street level, from where they reach a floating path through sculptures resonating Alberto Giacometti’s corporeal works, placed amidst the cistern piers, creating a perfect counterpoint to these massive structural elements. 

As a metaphor to the shorter branches of the historic aqueduct, visitors encounter whimsical staircases along the floating path, which they can climb to view the space from a different height. The path ultimately leads to a new temporary exhibition space below the ruin’s footprint, partially revealed through the underwater circular skylights, that located directly below the openings in the historic barrel vault, can be seen alongside the floating route.



A new lover level space is added to exhibit contemporary art, while housing a conference room and toilets in two soft-edge translucent volumes. Framed by a sinusoidal concrete slab alluding to the ancient vaults, it grants visitors an unprecedented view of the monument through the ocular skylights. The solid undulating slab rests on round concrete columns and retaining walls that safeguard the existing foundation. After exploring this space, visitors are led back to the atrium created below Via Mirabile NW, where water cascades down the reflective pool above, enhancing the immersive spatial experience. The atrium finally leads visitors straight towards the bookshop or upwards to the bar/café mezzanine, accessible both from a staircase and a lift, offering new views of the art and the former cistern.



The ruin’s rooftop is turned into a public space featuring a winding reflective pool that responds to the mimicked aqueduct path from below by having its walkable surface replaced with water, a playful element that could also help cooling high temperatures down. This new limestone-paved raised deck, sitting on a steel structure, pays homage to this typical Southern Italy material, highlighting a continuous sculptural bench and slightly inclined planes representing the old aqueduct’s branched configuration. At street level the NE Via Mirabile is pedestrianized and along with the remaining streets surrounding the building, the existing paving is replaced with regular basalt rock. The goal is to create a "buffer zone" around the monument to stress its significance and distinctive character.
