The use of this spring dates back to time immemorial. The discovery of Roman-era wall remains in the immediate vicinity shows that, as far back as two thousand years ago, the area was frequented and valued for the purity of its waters.
During the Renaissance, the fountain was such an important geographical and defensive landmark that it was specifically mentioned by Marquis Ludovico II Gonzaga. In no fewer than three official letters (dated 8, 17 and 20 May 1461), written during the castle’s renovation works, the Lord of Mantua refers to ‘the wall of the revellin and San Biagio towards the fountain’, confirming the strategic link between the upper fortress and the spring below.
The name ‘Torcolo’ itself seems to derive precisely from this glorious era: in the vicinity of the spring stood an ancient residence equipped with a press (torcol in the local dialect) for pressing olives and grapes, which had already been recorded in the Gonzaga registers.
