Ghella is an Italian and international civil engineering company,[1][2] specialized in the construction of large public infrastructural works and underground excavations through the use of tunnel boring machines.

During the pandemic period, Ghella supported the exhibit and catalog INSIEME, a project conceived by Gianni Politi and promoted by Roma Capitale, Sovrintendenza Capitolina ai Beni Culturali.

The exhibit was realized inside the Aurelian Walls to display the works of 19 artists and build a dialogue between monument and contemporary[31] In 2021, Ghella commissioned a series of photographic campaigns on construction sites in Europe, the Far East and Oceania.

The works were collected in the catalog “Di roccia, fuochi e avventure sotterranee” curated by Alessandro Dandini de Sylva [32] and displayed in an exhibit at the MAXXI museum in Rome.

In 2024, Ghella inaugurated a second photography exhibition at the MAXXI – National Museum of 21st Century Arts in Rome, curated by Alessandro Dandini de Sylva, called "Nuove avventure sotterranee" (New Underground Adventures).
