Hot springs by janchan
As in the ancient Rome, Romans love the hot-springs. The area around Rome is vulcanic, so there are several places where you can find hot water coming from the underground. Hmmmmmmm.... a so relaxing experience !! In the pic the 'Bullicame' near Vetralla (VT)... about 80 km north-west of Rome.
