Source of health
In the Navegna valley, at the same altitude as Casa Rea, there is a spring of iron-rich water. This spring was referred to in 1856 (Chorographical Dictionary of Italian-speaking Switzerland by Guglielmo Stefani) as being a potential location for a spa but one was never built. Popular belief suggested it possessed healing properties. In the past, the schoolchildren of Minusio were taken to drink from this spring as its water – which has a slightly acidic, pungent taste – contained carbonic acid, lime, a small amount of magnesia and iron. Its strong taste was not pleasant, but the pupils gulped it down because of its health benefits.
