The Fontana del Rosello at the bottom of the steps on Corso Trinità is the most celebrated monument in Sassari, a late Renaissance fountain of white marble fed by a natural spring. The fountain dates from the early 17th century and is decorated with figures of the seasons, allegorical reliefs, and two lions at the top holding the arms of Sassari.
The fountain sits at the base of a long stone staircase that descends from the old town, and the approach down the steps reveals the fountain gradually, with the dome of the cathedral visible above. The surrounding area has been somewhat restored but retains its historic character. This is the traditional meeting point of Sassari, and locals still come to sit on the steps in the evening.
