Palazzo della Zecca, Royal mint palace in Naples, Italy

Palazzo della Zecca is a monumental palace on Via Sant'Arcangelo a Baiano in Naples. Its main facade, the best-preserved original part, rests on a rusticated base with a portal leading to a coffered vestibule and then a courtyard with two orders of openings. The west side has superimposed arches framing piperno stone cornices, and a richly decorated 19th-century portal faces the vestibule.

The palace was built in the 13th century and later became the royal mint, where official coins of the Kingdom of Naples were struck from 1528 to 1867. Its role as a mint ended in the 19th century as the city's economic and administrative infrastructure changed.

The western wing displays a sequence of overlapping arches framing piperno stone cornices, a volcanic material typical of Naples. This stone type shapes local architecture and gives the building its distinctive appearance.

The building is accessible from multiple directions, particularly through the main entrance and the additional facade facing Rettifilo avenue. The interior layout with a vestibule and courtyard makes navigation easy when exploring the space.

The courtyard features two superimposed levels, each with its own arches and openings that create layered visual patterns. This stacked arrangement shows how medieval and early modern architectural styles were literally built on top of each other in Naples.
