The religious feast and late-August fair in Castro dei Volsci
This edition has not been confirmed by the organiser to date. We recommend checking before going.
The Festival of Maria Santissima del Piano is one of the most deeply rooted traditions in Castro dei Volsci, a village in the province of Frosinone, located in the Ciociaria region, the heart of the Lazio Valle Latina. The focal point of the festivities is the Madonna del Piano area, the flat part of the municipal territory where the sanctuary dedicated to the Virgin stands, a destination of devotion for the entire local community and neighboring towns.
Tradition links this veneration to a medieval origin story: a wooden statue of the Madonna and Child, kept in Castro dei Volsci, is said to have mysteriously disappeared from its chapel only to reappear in nearby Ausonia. That event sparked a deep fraternal bond between the two communities, passed down through the centuries via a pilgrimage that, in more recent times, is repeated every three years and involves the exchange of banners between the towns. This shared memory gives the Castro festival an identity value that goes far beyond a single day of celebration.
On the last Sunday of August, the plain comes alive from the morning. The religious program includes Eucharistic celebrations, moments of prayer at the sanctuary, and the solemn procession that accompanies the statue of the Madonna among the faithful. Alongside the liturgical aspect, the popular dimension of the festival unfolds with the historic fair, stalls selling local products, sweets, and handicrafts, and evening entertainment that attracts both residents and emigrants returning for the summer.
Like many patronal feasts in southern Lazio, the event intertwines Marian devotion with the village's social life: it is an occasion where families, brotherhoods, and local associations reunite, where shared rites are renewed, and where the historical agricultural calendar marks a festive pause at the end of summer. Collaboration between the parish, the Municipality of Castro dei Volsci, and the Pro Loco ensures the organization of the events and the welcoming of visitors every year.
The festival is also a great reason to visit Castro dei Volsci, one of the most characteristic hilltop villages in the Lazio Region, with its medieval historic center, panoramic views over the Valle Latina, and the nearby archaeological area of Casale di Madonna del Piano. Those arriving for the Marian celebration will find, beyond the religious dimension, a heritage of history and landscape waiting to be explored.
The Marian observance of Castro dei Volsci is expected, as is customary, on the last Sunday of August (August 30, 2026), at the Madonna del Piano area, in the province of Frosinone. The day is expected to include, as per tradition, Eucharistic celebrations at the sanctuary, the solemn procession with the statue of the Madonna, and the popular part of the festival, with the fair, market stalls, and evening entertainment.
The detailed program, service times, and side events are usually released by the Municipality of Castro dei Volsci and the parish in the weeks preceding the festival. It is recommended to check dates and updates on the official municipal channels before traveling.
