Palazzo Fienga, Medieval fortress and 19th-century palace in Nocera Inferiore, Italy.

Palazzo Fienga is a 19th-century building in Nocera Inferiore that preserves features of a medieval fortress. The structure contains two courtyards, with a medieval tower integrated into the first courtyard and defensive walls surrounding the second courtyard.

The De Guidobaldi family, barons of Sant'Egidio, bought the castle area in the early 19th century and built a structure beside the medieval walls without erasing them. The chapel with a dome dedicated to Nostra Signora Mater Domini was built in 1850 by Baron Francesco De Guidobaldi. The Fienga family completed the current palace in the early 20th century.

The Fienga family, known for its collecting passion, gathered about 3,000 Roman finds and set aside a whole wing of the palace to display them. The collection was cited in the 1950 Annuario dei Musei e Gallerie d'Italia, published by the Libreria dello Stato.

The building is managed by the Municipality of Nocera Inferiore and welcomes visitors to explore its interior spaces and collections. It is best to check opening times in advance and wear comfortable shoes for walking through historic areas.

The Teatro Virtuale della Valle del Sarno occupies the palace conference room and seats 96 people. Visits are by reservation only, and the virtual tour runs through reconstructions of sites across the Nocerino-Sarnese plain, from the eighth-century BC Tomba della Principessa of San Valentino Torio to the first-century AD Villa rustica of Numerius Popidius Narcissus Maior at Scafati.
