Inside view of the thermal structures in Bath, Somerset, United Kingdom.
Springs and wells were frequently regarded as sacred places, and many of them were believed having therapeutic properties for different kinds of diseases and afflictions. Particularly sacred were the thermal springs, where hot waters gushed out from the deep of the earth, as at Bath (the ancient Aquae Sulis), in South-Western England, where the healing properties of thermal waters had been known and utilized for over two thousand years. Here, the Celtic local divinity, called Sul, was identified by the Romans with Minerva Medica, to whom they devoted the imposing structures that can be observed still today. The practice of throwing coins in springs or waterholes as offering to the divinities and as propitiation of wellbeing and good fortune dates back to the Celtic age. Thousands of coins have been discovered in the spring of Bath, the most of them dating to the Roman period.
