From whichever part of the city you are coming, surrounded as it is by steep slopes, the flatness of the square will be a surprise. Its pavement is supported by a monumental system of cisterns built in Roman times, which supported the Forum, the public square of the ancient town of Tuder, which was even larger than the medieval and current square.
The Roman cisterns, a fine work of hydraulic engineering to supply water to the hill, are part of an impressive underground tour, which will take you through the network of wells, tunnels and cisterns from various eras.
To fully appreciate the square and its colours, we recommend a visit around lunchtime, when the sunlight is at its strongest, enhancing the whiteness of the stone with which the public buildings are built. Admire the piazza while enjoying an aperitif, perhaps sipping a glass of DOC wine, delighting in the typical habits and rhythms of small Italian towns, which use the squares as places to walk, rest, meet and socialise.
