GrottaStellata

A week of cinema under the stars in Grottaferrata

GrottaStellata is the summer open-air cinema festival that brings the Giardini di Patmos to life every July in the heart of Grottaferrata, in the province of Rome, Lazio. Launched in 2022, the event has quickly established a local tradition: seven consecutive evenings, one screening per day at 8:45 PM, free admission, and mandatory online booking. In 2026, the festival celebrates its fifth edition.

Who organizes it

The project is conceived and curated by the Associazione Archè APS, a local cultural promotion group, in collaboration with the Grottaferrata Youth Council, the L'Anima Conta association, and the Pro Loco of Grottaferrata, with the patronage of the Municipality. It is a distinctly participatory model: the festival is not just a film schedule, but a community project built largely by volunteers and local youth.

A thematic festival, different every year

What sets GrottaStellata apart from many other summer arenas in Lazio is the choice to give each edition a thematic thread declared in the subtitle. The 2025 edition was titled Cinema Beyond Illusion and featured titles that question appearances and media narratives; the 2026 edition changes pace with Oscar-Winning Cinema, a week entirely dedicated to Academy Award-winning films, ranging from auteur thrillers to family animation. The programming deliberately mixes genres and audiences: a challenging drama might follow a comedy or an animated film, ensuring every evening has its own audience.

The Giardini di Patmos

The venue is one of the most beloved green spaces in Grottaferrata, located on Via Garibaldi, just a few steps from the town center and the famous Abbey of San Nilo, the Greek-Byzantine monastery founded in 1004 that serves as the city's symbol. The garden is equipped with a screen, sound system, and seating: the atmosphere is that of a rare, neighborhood open-air cinema, with the Castelli Romani hills surrounding it and the evening breeze making the viewing experience much more pleasant than an indoor theater in July.

Why it's worth a visit

• Free admission for all evenings, with mandatory booking on the official website.
• One screening every evening for seven consecutive days, always at 8:45 PM.
• Thoughtful programming built around a theme, not just a sequence of commercial titles.
• An excellent opportunity to combine the evening with a stroll through the historic center and dinner at the local fraschette (traditional taverns) of the Castelli Romani.
• Easily accessible from Rome, just over twenty kilometers from the capital.

The context of the Castelli Romani

Grottaferrata is part of the Castelli Romani, the hilly area southeast of Rome known for the white wines of the Colli Albani, porchetta, and a dense network of summer festivals and food fairs. In this crowded calendar of gastronomic events, GrottaStellata occupies a different and complementary space: a free cultural offering, designed primarily for residents but perfectly accessible to those arriving from Rome or neighboring towns for an evening outdoors.
