 This study examined the microclimate inside the Church of San Panfilo in Tornempart, Italy. It focused on the preservation of the frescoes painted by Saturnino Gatti in the 1490s. To do this, the researchers conducted a measurement campaign from February 2021 to April 2022. They took measurements at different locations within the church and also continuously monitored the environment over the course of the year. The team then analyzed the data collected to determine the daily and monthly values, as well as the effects of the building on the environment. The results showed that the frescoes are vulnerable to certain conditions, such as high temperatures or sudden changes in temperature and humidity. Additionally, the researchers found that the historic climate of the church can be detected through the data they collected.
