Description

 

Welcome to Rome’s Most Breathtaking Palace

 

Of all the grand palaces in Rome, Palazzo Colonna may be the most breathtaking. The private home of one of the city’s oldest noble families - its ranks include popes, cardinals, and military leaders - the palace reached its peak in the 17th century when the Colonna transformed it into a dazzling showcase of Baroque art and luxury. Today, its soaring galleries and gilded halls house one of Rome’s finest private collections of art, where frescoes glorifying the family seem to lift the very stone of its vaults to the heavens. Open only on Saturday mornings until 2 PM, a visit here offers a rare chance to experience the full drama and beauty of Baroque Rome.

 

Meet One of Rome’s Most Powerful Dynasties

 

Long before the palace’s Baroque splendor took shape, the Colonna family was already a force to be reckoned with in medieval Rome. On our tour we’ll discover how the Colonna family carved its place in Roman history.  Learn how they rose to prominence as fearsome feudal barons, their fortunes intertwined with the tumultuous politics of the Papal States. In 1303, Sciarra Colonna’s infamous slapping of Pope Boniface VIII at Anagni marked one of medieval Italy’s most dramatic power plays, an act that shook Christendom and precipitated the papal court’s exile to France for the next seven decades.

From these turbulent origins emerged Oddone Colonna, who in 1417 was elected Pope Martin V and ended the Western Schism, restoring stability - and enormous prestige - to Rome. His fourteen‑year reign not only launched vast urban renewal projects but also cemented the family’s status at the heart of Renaissance culture. Today, as you prepare to step through the palace doors, remember that every gilded cornice and frescoed ceiling reflects the fierce ambition and centuries‑long legacy of this extraordinary dynasty. 

 

From Fortress to Baroque: The Evolution of Palazzo Colonna

 

Before the Colonnas summoned Baroque masters to adorn its interiors, Palazzo Colonna began life in the early 14th century as a fortress‑like compound typical of Rome’s feudal barons. Thick stone walls, narrow towers, and fortified courtyards spoke to the family's need for defense in an era of rival clans and papal power struggles. In 1420, Oddone Colonna - soon to be Pope Martin V - elevated the residence to an official papal palace, prompting incremental Renaissance‑style additions that began to soften its medieval austerity. 

It wasn’t until the late 16th century that the palace we recognize today began to emerge. Prince Filippo I Colonna embarked on an ambitious project to unify a labyrinth of medieval and Renaissance buildings into a coherent whole, reshaping courtyards, expanding reception rooms, and harmonizing façades. As the seventeenth century drew to a close, the palace stood fully reborn: a theatrical showcase of Baroque ideals that reflected the position of the Colonna at the apex of Roman society.

 

Baroque Splendor Unveiled: The Great Hall

 

At the core of the palace lies the Great Hall, a 70‑meter-long gallery that is every bit as grand as Versailles in its Baroque extravagance. Commissioned by Lorenzo Onofrio Colonna in the 1660s, this vast salon was conceived as both a celebration of family glory and a showcase for the Colonna art collection. Mighty pilasters and columns hewn from rare giallo antico marble line the walls. 

Above, exuberant frescoes animate the ceiling with the swirling drama of the 1571 Battle of Lepanto, when Italian fleets commanded by Marcantonio Colonna defeated the fearsome Ottoman navy. This was one of the greatest triumphs in the story of the Colonna family, and it’s given a truly spectacular showcase here: gaze up as Italian galleys cleave through painted waves, Turkish vessels billow in exotic finery, and Marcantonio himself is received into heaven by the Virgin Mary in a blaze of celestial radiance. 

As you pause beneath these soaring vistas, your guide will unravel how art and propaganda merged here to immortalize the family’s legacy in marble, pigment, and light. 

 

A Panorama of Masterpieces: The Galleria Colonna

 

Continuing your private tour, step into the halls that house the Galleria Colonna’s painting collection. Built up over generations of careful patronage and a keen eye for quality, the Colonna family’s art collection ranks among the most exceptional private galleries in all of Rome. As you tour the lavishly decorated rooms, your guide will help you discover an astonishing array of masterpieces: from razor-sharp portraits of 17th-century nobility to sweeping religious scenes, lush pastoral landscapes, and dazzling allegories.

Annibale Carracci’s unforgettable Bean Eater (Il Mangiafagioli), might just be the collection’s highlight: one of the first true genre paintings in Western art, this earthy, unsentimental portrait of a peasant mid-bite was revolutionary in its day and went on to influence artists like Van Gogh and Degas centuries later. 

You’ll also encounter works by some of the biggest names in Renaissance and Baroque painting - Veronese, Tintoretto, Rubens, Perugino and Andrea del Sarto are just the beginning.  Look out for Bronzino’s Venus, Cupid and a Satyr, a striking embodiment of Mannerist elegance, filled with sensuous curves and intellectual complexity. 

 

Portraits of Power: The Isabella Apartments

 

Step beyond the grandeur of the main galleries and discover a more intimate side of Palazzo Colonna as your guide leads you into the private world of Princess Isabelle’s apartments. Tucked away from the ceremonial splendor of the Great Hall, these richly decorated state rooms and personal chambers offer a rare glimpse into aristocratic life behind closed doors. Here, gilded mirrors, family portraits, antique tapestries, and lovingly preserved furnishings speak of generations of privilege and refinement.

As you explore these spaces - once frequented by royals, popes, and heads of state - you’ll hear stories of Princess Isabelle’s legendary hospitality and the vital role she played in preserving the palace’s cultural legacy through some of the most turbulent years of the 20th century. From elegant drawing rooms to opulent salons decorated by Caspar van Wittel's superb landscape paintings, each room feels like a private vignette of European high society, still echoing with the moemories its former residents.

 

A Breath of Fresh Air: The Secret Garden and Terrace

 

After immersing yourself in the opulence of the Galleria Colonna, step outside to discover palace’s enchanting terraced gardens on the Quirinal Hill. Featuring manicured boxwood hedges, citrus trees, and classical sculptures, the gardens, once a private haven for the Colonna family, now offers up a peaceful retreat for visitors from the never-ending bustle of Rome - just meters away but a world apart.
