Churches and Hypogea

This chapter considers two different types of environments, churches and hypogea, that share some common characteristics: they are indoor environments, and contain a great variety of culturally and artistically interesting works (paintings, vestments, sculptures, etc.), though their function is not conservation; moreover they are usually not equipped with heating, lighting or ventilation systems that have been calibrated and controlled for a correct conservation of the works of art. For other aspects, on the contrary, churches and hypogea are decidedly different from each other, particularly if they are considered from a microclimatic point of view; for this reason, we shall analyse them separately.
