Palazzo dei Congressi, Art Nouveau palace in Salsomaggiore Terme, Italy.

Palazzo dei Congressi occupies the former Grand Hôtel des Thèrmes, a five-storey building on a horseshoe plan with a basement and attic. The main facade carries Art Nouveau decoration: an iron canopy by Alessandro Mazzucotelli over the entrance, floral ceramic architraves by Gottardo Valentini, and a rear wing added in 1927 facing the park, beside the Auditorium Europa.

Commissioned in 1898 by the Società Magnaghi, the Grand Hôtel des Thèrmes was designed by Luigi Broggi with advice from César Ritz and Alphons Pfyffer, who ran it from its 1901 opening and owned it from 1910. After World War I, Riccardo Ferrario had Ugo Giusti and Galileo Chini add the Salone Moresco and Taverna Rossa, inaugurated in 1926. The comune bought the building in 1966 and converted it into the Palazzo dei Congressi.

The Salone Moresco and the Taverna Rossa beneath it were decorated by Galileo Chini in a style mixing Moorish and Chinese motifs. The Taverna Rossa, opened in 1926 with shows staged for the occasion, has coffered red ceilings with circular geometric patterns and frescoes of herons, peacocks, fish and jellyfish. Its lacquered Chinese-style furniture came from the Lucca cabinetmaker Franco Spicciani.

The 17 conference rooms sit on four levels and hold up to 2,300 people in total; the municipal library occupies the basement, the paleontological museum the third floor. The levels are linked by a marble-and-iron staircase with frescoed walls and by lifts, one of them original. The entrance is on viale Romagnosi 7, facing the piazzale restored between 2006 and 2011.

The basement Taverna Rossa, designed by Galileo Chini in a Moorish-Chinese style, has coffered red ceilings and frescoes of herons, peacocks, fish and jellyfish. Its original red-lacquered Chinese-style furniture and chandeliers were made by the Lucca cabinetmaker Franco Spicciani. It was created for masked balls and small concerts and is now used for meetings and exhibitions.
