Pantheon
Pantheon, Roman temple in Pigna district, Rome, Italy
The building presents a cylindrical brick rotunda measuring 43.3 meters in diameter, crowned by a hemispherical concrete vault. The vault contains a central opening of 9 meters in diameter serving as the sole light source. The front portico features sixteen Corinthian granite columns supporting a triangular pediment.
Marcus Agrippa erected an initial temple in 27 BCE, destroyed by fire under Domitian. The present construction arose between 113 and 125 CE under Emperor Hadrian, retaining the original Agrippan inscription on the facade. Pope Boniface IV consecrated the structure as a church in 609, preventing medieval plundering.
Serving as a Catholic church for over 1,400 years, the building houses tombs of Italian monarchs including Victor Emmanuel II and Umberto I, along with the painter Raphael. Its dedication to Santa Maria ad Martyres in 609 made it the first Roman cult site converted from pagan to Christian use.
Entry remains free Monday through Saturday from 8:30 AM to 7:15 PM and Sunday from 9:00 AM to 5:45 PM. Visitors can walk from Piazza Navona in 5 minutes or from Trevi Fountain in 8 minutes. The nearest metro station is Barberini on Line A, a 15-minute walk away.
The vault was constructed using Roman concrete cast with pozzolanic volcanic ash and graduated material layers, employing lighter pumice stone at the apex to reduce weight. This ancient technique allowed the unreinforced structure to endure nearly two millennia without steel reinforcement or modern support systems.

This collection brings together notable domes and cupolas from all continents, signs of diverse architectural traditions extending from the Vatican to Australia, Russia to the United Arab Emirates. From the famous dome of St. Peter's Basilica in Rome to the colorful domes of the Church of the Savior on Spilled Blood in Saint Petersburg, the Renaissance dome of Florence Cathedral, to the cast-iron dome of the US Capitol in Washington, each structure tells a particular story and reflects the ambitions of its era. These buildings span several centuries of architectural innovation and serve various functions: religious structures like the Sheikh Zayed Grand Mosque or the Basilica of Our Lady of Peace in Côte d'Ivoire, civil buildings such as Oxford's Radcliffe Camera or the Australian Exhibition Palace, and even thermal spas like Budapest’s Széchenyi Baths. Each dome illustrates construction techniques and aesthetic decisions specific to its culture, offering insight into skills that enabled the creation of these monumental coverings.
Circular architecture has fascinated builders since ancient times. This collection brings together Roman amphitheatres like the Colosseum, medieval towers such as the Round Tower in Copenhagen, baroque domed structures and modern constructions. The circular form offers practical advantages for acoustic properties, structural stability and optimal space usage. The selected buildings serve various functions: religious temples, fortifications, observatories, museums and event venues. Each example demonstrates how architects have adapted the circular form to local conditions and cultural requirements. From ancient stone structures to contemporary skyscrapers, this selection documents technical evolution across centuries.
Rome contains over 900 churches that demonstrate two thousand years of sacred architecture, from Roman antiquity to the Baroque period. These buildings reveal the evolution of construction techniques and artistic expressions over the centuries. St. Peter's Basilica covers 20,000 square meters and features a dome designed by Michelangelo. The Pantheon retains its Roman dome with a 43-meter (141 feet) diameter, the largest ever constructed in unreinforced concrete. Major basilicas such as Santa Maria Maggiore showcase Byzantine mosaics from the 5th century beneath a Renaissance ceiling with gilded coffers. Saint Clement's Basilica in the Lateran overlays three levels of construction from the 1st to the 12th centuries, illustrating Rome's urban stratification. Santa Maria in Trastevere, one of the city's oldest churches, presents medieval gilded mosaics, while Saint Peter's in Chains houses Michelangelo's Moses. These monuments help understand how Rome shaped European religious architecture for over fifteen centuries.
Rome combines ancient history with modern photography. The city presents monuments, fountains, squares and viewpoints to photographers. The Colosseum, Castel Sant'Angelo and Roman Forum display Roman architecture. The Vatican Museums and Piazza Navona showcase art. The Villa Borghese Gardens and Trastevere district complement the urban setting.
