In the early 1980s, Ceccobelli and other artists settled in the former Pastificio Cerere, a large abandoned industrial space located in the San Lorenzo quarter in Rome.

The group, known as the New Roman School or San Lorenzo Workshop,[4] included Piero Pizzi Cannella, Marco Tirelli, Giuseppe Gallo, Gianni Dessì, Nunzio Di Stefano and Domenico Bianchi.

In 2004, Ceccobelli realizes the mosaic "Eternity is the true healer" in Gibellina (Sicily) and the year after the Guastalla Gallery in Livorno presents the anthological exhibition "Big Works 1989-2005".

In 2006, Ceccobelli presents a series of marble sculptures in Verona and in Pietrasanta at the gallery Spirale Arte, and participates in the important group exhibition "San Lorenzo" at Villa Medici (Roma).

Also in 2009, the Museum of Contemporary Art (MaRT) of Rovereto presented the first retrospective exhibition dedicated to the Officina San Lorenzo, which traced the history of that group.

It is also the year of the participation in the important exhibition "Grandi opere…grandi" at the Marconi Foundation (Milan) and in the Lazio Stand at the Venice Biennale (curated by Vittorio Sgarbi).

In 2012, Ceccobelli presents his solo-exhibition "Eroi d’Eros" (Catania), which collects 101 erotic drawings, then at the Museum of modern Art in Buenos Aires, Argentina (2013).

In 2014, the solo exhibitions are: "Summa Felix" in Cosenza at the Vertigo Arte Cultural Association, full of his pictorial well known symbols; furthermore "Terra Cotta" at the municipal space La Rinascente in Padova, with an anthology on the twenty-years production of his ceramics, and with the participation of his sons Auro and Celso; and "Port'Ostensorio" at the Susanna Orlando gallery in Pietrasanta with some consecrated host-shaped paintings blessed by art.
