Palazzo di Sangro di Casacalenda

One of the most prominent churches of Naples. This Gothic church (est. 1283) incorporates a smaller, original church built on this site in the 10th century, San Michele Arcangelo a Morfisa. The monastery annexed to the church has been the home of prominent names in the history of religion and philosophy. It was the original seat of the University of Naples, where Thomas Aquinas, a former monk at San Domenico Maggiore, returned to teach theology in 1272. As well, the philosopher monk, Giordano Bruno, lived here. The sacristy houses a series of 45 sepulchres of members of the royal Aragonese family, including that of King Ferdinand I.

A chapel built in 1590, it contains sculptures and other works of art by some of the leading Italian artists of the 18th century, like the extraordinary Veiled Christ by Giuseppe Sanmartino. It also has a high scientific interest because it hosts the anatomical machines, a still mysterious experiment by Raimondo Di Sangro, a prominent Renaissance scientist. In addition, in the basement there are two human vein models, looking like plastination. Because of the small size, the waiting queue may be longer than at other attractions in Naples.

A religious complex which includes the Church of Santa Chiara, a monastery, tombs, and an archaeological museum. The double monastic complex was built in 1313-1340 by Queen Sancha of Majorca and her husband King Robert of Naples. The original church was in traditional Provençal-Gothic style, but was decorated in the 1744 century in Baroque style by Domenico Antonio Vaccaro. Santa Chiara was the largest Clarissan church ever built, and it was the first Clarissan church built where the nuns in their choir would have been able to view the performance of Mass. The bell tower, separated from the main edifice, was begun in 1328 but was completed only in Renaissance times. The simple interior houses the tomb of King Robert and, in the side chapels, those of the Bourbon king of Naples, Francis II and his consort Maria Sophie of Bavaria, as well as of Queen Maria Christina of Savoy and of the national hero Salvo d'Acquisto (a carabiniere who sacrificed his own life to save the lives of 22 civilian hostages at the time of the Nazi occupation). Famous is the cloister of the Clarisses, transformed in 1742 by Vaccaro with the addition of precious majolica tiles in Rococò style. The Nuns' Choir houses fragments of frescoes by Giotto.

The Church of Gesù Nuovo (New Jesus) was built in 1470 as a palace for Roberto Sanseverino, Prince of Salerno. The Jesuits had already built a church in Naples, now called Gesú Vecchio. Political intrigues caused the property to be confiscated, and eventually sold in the 1580s to the Jesuits to construct a church (1584–1601) under architect Giuseppe Valeriano. The unusual façade, unusually plain for a Baroque style church, is of rusticated ashlar and is the original façade of the palace. The church contains masterpieces of some of the most notable Neapolitan artists: Belisario Corenzio, Paolo de Matteis, Francesco Solimena, Giovanni Lanfranco and Massimo Stanzione.

The church was completed in 1640, in honor of Saint Gregory of Armenia and it represents, along with the adjacent monastery, one of the most relevant Baroque complexes in Naples. The interior is decorated with 52 frescoes by Luca Giordano, and it is characterized by a single nave with five side arcades and chapels, in an impressive triumph of Baroque decorations.

Presents ruins of a former Roman market - shops and the like. In addition, entrance to the surrounding museum and chapels is included.
