Marble Wall Mosaic: Acqua Vergine uses marble in such an illustrious way that it doesn’t even feel like an area for an indoor pool. Taking its cues from Rome, where the Roman aqueducts delivered pure drinking water to Rome, the water flows through the room and delivers greatness at every corner. With so many gorgeous touches, it’s easy to see the similarities with other great architectural works of art that also get their water from the Roman aqueducts – the Trevi Fountain and the Piazza del Popolo.
