In 1989, Socrate Sensi, a businessman and knight of the order of merit for labour from Viterbo began renovating and modernising the entire municipal Spa, and opened it to the public in 1993. Ever since then, the Terme dei Papi has established an increasingly solid foothold on the thermal wellness and health market, and has even been ranked in the Top Superior Category thanks to the effectiveness of its thermal treatments. To this day, Terme dei Papi is still managed by the children and grandchildren of Socrate Sensi.
