Piazza Maggiore is a central square in Bologna, region of Emilia-Romagna, Italy, largely preserving its 15th century layout. The Northwest corner opens into Piazza del Nettuno with its Fontana del Nettuno, while the Northeast corner opens into the narrower Piazza Re Enzo, running along the flanks of the Palazzo Re Enzo that merges with the Palazzo del Podestà .
