Piazza Grande, Residential complex in Ponti Rossi, Naples, Italy

Piazza Grande is a residential complex in the Ponti Rossi area of Naples, built 1979–1989 to a design by Aldo Loris Rossi, Donatella Mazzoleni, Annalisa Pignalosa and Luigi Rivieccio. Its circular plan wraps a hillside with a convex quadrant; a 100-metre-diameter central space, a hanging park with a 26-metre opening at its centre, is ringed by a low circular building. Twelve radial service towers serve six residential towers 36 metres tall, five round and one rectangular.

The complex was built between 1979 and 1989 to designs by the Neapolitan architects Aldo Loris Rossi, Donatella Mazzoleni, Annalisa Pignalosa and Luigi Rivieccio, in the Ponti Rossi area. It draws on Frank Lloyd Wright's organic architecture and Italian Rationalism, and above all on the Royal Crescent and the Circus in Bath. In 1989 the project received the In/Arch prize of the Istituto Nazionale di Architettura.

The circular central space, 100 metres across, was conceived as a reception area for visitors to the whole complex and doubles as a hanging park with flowerbeds, tree-lined gardens and sports facilities. Locals nicknamed the round residential towers "i bicchieri" (the glasses) because of their shape, a name that stuck even among those who disliked the look.

Vehicle and pedestrian routes are kept on separate levels, so visitors arriving by car reach the garages and stores below while walkers use the upper paths. The central hanging park slopes down toward the sports facilities, forming a small stepped seating area beside them.

Six of the twelve radial service towers serve residential towers 36 metres tall: five with a circular plan and one rectangular. Locals call the round ones "i bicchieri" (the glasses), a nickname coined because many disliked their look.
