Stayed at the Hotel Heluan and had this beautiful with view of the Hot Spring Colonnade and the Church of St. Mary Magdalene from my room.
Hot Spring Colonnade (in front of the church under glass) can spurt up to the height of 12 meters and in one minute it can shoot
up to 2000 litres of thermal mineral water at the temperature of 72 °C and 5000 litres of carbon dioxide.
The Hot Spring water from the underground colonnade is supplied to the spa hotels, which are using it both for bathing, as well as for drinking cures.
