On the ramp leading to the stairway is the mezzanine housing an interesting collection of 19th and 20th century paintings. Halfway up the stairway, the imposing doorway comes into view at the top, with fluted pilasters from the now demolished church of S. Maria dei Piattelletti (1480). In the centre of the room on the right is the original bronze of the Statue of Fortune made by Donnino Ambrosi in 1593 for the fountain in the piazza. On the walls are 12 small oil paintings and a fine series of engravings recording the work done by the great scenographer and theatrical engineer Giacomo Torelli (1604-1678) for the theatres of Paris and Venice. There are also coin-cases against the walls containing the most interesting items in the collection of Roman, medieval and modern coins, including those struck at the mint of Fano (15th to 18th century), the wonderful series of Malatesta medallions by Matteo de Pasti (1446) and those by Paolo Sanquirici to commemorate the construction of the Porto Borghese (1613).
	Established in 1898 in the north-east wing of the Malatesta Palace, it conserves numerous paintings dating from the 14th to the 20th centuries. The "Sala del Caminetto" houses paintings of the 14th and 15th centuries, among which are worth noting the Polyptych of "Madonna and Saints" attributed to the Venetian painter Michele Giambono and the painting by Giovanni Santi of "Madonna and Child enthroned with Saints". In the "Sala Grande" are paintings from the 16th and 17th centuries, mainly from religious buildings. These include Guercino’s “Guardian Angel”, "Saint Nicholas of Bari in Glory” by Mattia Preti (nicknamed the “Calabrian Cavalier”) and fine paintings from the baroque Church of San Pietro in Valle, including a splendid "Annunciation" by Guido Reni, "Saint Peter raising Tabitha" by Matteo Loves and "Saint Peter healing the cripple" by Simone Cantarini. The "Sala Morganti" contains paintings from the 18th century, including those by the Fano painter Sebastiano Ceccarini, while the last room houses a collection of 15th - 19th century ceramics.
	The name of the library is that of its founder, Abbot Domenico Federici (1633-1720). After a busy life as a diplomat at the court of Vienna, panegyrist, poet laureate and bibliophile, he set up the library at the congregation of the fathers of St.Philip Neri in Fano, which he entered in 1681, and to which he left his books, provided they were put at the disposal of the public for at least an hour a day. The building now partly rebuilt and entirely restructured, was the residence of the fathers of St.Philip Neri until the unification of Italy, after which the library was taken over by the town council, which has continued to keep it open to the public. New acquisitions have regularly been made and the library is one of the most considerable in the region. On the first floor at the head of the elegant 19th century staircase is the original "Sala dei Globi" (Globe Room), arranged by Federici between 1678 and '80, named after a pair of globes (of the earth and the heavens), made in 1688 by the famous Venetian cosmographer P. Vincenzo Coronelli. The beautiful original walnut-wood bookcases carved by Francesco Grimaldi from Bologna are still as they were, holding the volumes which belonged to Abbot Federici in their fine original bindings in the French style. There is also a valuable Nautical Chart drawn by the Genoese cartographer Visconte Maggiolo in 1504. The chart indicates all land up to then known and explored (from the Antilles to the Brazilian coast; from the coast of Africa to the Indian peninsula). On the courtyard walls, in the entrance hall and along the stairs there are numerous friezes, architraves, corbels and coats of arms from the greatest patrician dwellings of Fano. The library today consists of over 200,000 printed works, including a fair number of incunabulae (books printed before 1501), some thousands of volumes printed in the 16th century (including several editions printed by Soncino) and rare 17th and 18th century atlases and volumes, some of them foreign. There are also numerous manuscripts, including some 15th century codices (one of which illuminated) and subsequent works, letters signed by the famous (Leopardi, Pellico, Verga, Capuana, Garibaldi, D'Annunzio, Eleonora Duse, inter alia), as well as plays and music. There is also a good collection of prints and drawings, photographic and newspaper libraries and the theatre archive of Fano.
