Boville Ernica (a town of approximately 8,000 inhabitants in Frosinone province, in the Ernici mountain zone of the Ciociaria, 90km southeast of Rome, the name "Ernica" derived from the ancient Hernici, the pre-Roman Italic people who inhabited this mountain zone before their incorporation into the Roman alliance in the 4th century BC) is the hill town where the finest Romanesque collegiate church in Lazio stands almost entirely unknown to the international visitor circuit that systematically favors the Romanesque of Tuscany and Umbria over the specific Lazio tradition. The Collegiata di Santa Maria Salome (the Romanesque church at the highest point of the Boville Ernica historic center, founded in the 8th century and rebuilt in its current form in the 12th-13th centuries) has a Cosmati-work floor (the specific Roman-Lazio marble inlay tradition of the Cosmati family of marble workers, which produced the colored geometric marble pavements of many Lazio and Rome medieval churches) and a portal of the specific 12th-century Lazio Romanesque style that combines antique marble spolia (columns and capitals taken from Roman buildings) with the original Romanesque architectural program in the manner specific to the Ciociaria zone.
The Boville Ernica polygonal walls (the pre-Roman Hernician fortification walls, opus polygonale masonry, surviving in sections on the western and northern edges of the historic center) are among the best-preserved examples of this pre-Roman building tradition in the Frosinone province, comparable to the Cori and Alatri polygonal walls but receiving a fraction of their visitors. The specific Boville Ernica wall character: the walls are integrated into the medieval urban fabric, with medieval and modern buildings constructed directly on the Hernician foundations, producing the specific layering of historical periods visible in a single wall section.

Boville Ernica: The Church and the Town
The Cosmati Floor of Santa Maria Salome
The Cosmati marble floor of the Collegiata di Santa Maria Salome is the primary reason to make the Boville Ernica detour: the geometric patterns of the Cosmati tradition (the interlocked circles, squares, and tessellated triangles in red, green, and white marble, with the specific porphyry discs, the rare imperial purple-red stone from the Egyptian quarry of Mons Porphyrites, which the medieval marble workers reserved for the central medallions of their most important floors) cover the entire nave and apse of the church. The Cosmati tradition is documented in Rome (the floors of Santa Maria in Cosmedin, San Clemente, Santa Maria Maggiore) and in the major Lazio churches (the Montecassino abbey Cosmati works), but the Boville Ernica floor is one of the finest provincial examples in a church that receives almost no visitors, the experience of a great medieval artistic tradition in its completely unmediated, un-restored, un-museum-ified form.
The Ernici Mountain Context
The Ernici mountains (the calcareous range that forms the southern boundary of the Ciociaria zone, rising to 2,247m at Monte Viglio) provide the specific landscape backdrop that makes the Boville Ernica visit more than just an architectural pilgrimage: the view from the church terrace over the Liri-Sacco valley and toward the Appennine ridges is the panoramic reward for the winding approach road. The Monti Ernici Natural Reserve (part of the Simbruini Regional Park) covers the upper mountain zone and is accessible for hiking from several Ciociaria towns including Boville Ernica.
Q&A: Boville Ernica
Is the Collegiata di Santa Maria Salome always open?
The church is regularly open for liturgical services (morning and evening) and generally accessible during daytime hours (approximately 9:00-12:00 and 15:30-18:30), but there is no permanent custodial staff and access outside service hours may require contacting the parish office. The Boville Ernica tourist office (at the comune) can provide current access information. The best strategy: arrive for the morning opening (9:00) when the church is accessible for the specific light on the Cosmati floor from the eastern windows.
Curiosità
Il Cosmatesco è una tecnica e una famiglia: i Cosmati non sono un nome di stile ma un nome di famiglia, i Cosma, i Lorenzo, i Giacomo di Pietro Cosmati erano marmorari romani del XII-XIII secolo che lavorarono in un sistema bottega-famiglia producendo i pavimenti, gli amboni, i cibori, e i portali delle chiese laziali e romane del periodo. Il termine "opus alexandrinum" (usato talvolta come sinonimo di Cosmatesco) si riferisce specificamente ai porfido egiziano e al serpentino verde, le pietre imperiali che i marmorari romani del Medioevo recuperavano dai monumenti antichi dismessi per incorporarle nelle loro opere cristiane.
