Sofia has no river but what seems to have attracted the first Thracian settlers was the presence of many hot springs. They are still there today and in downtown Sofia, just across from the former Sofia Central Mineral Baths, there is a small square where locals come to fill their bottles with mineral water. This water comes from the same spring that used to feed the Baths but they are no longer in use and the building is now the Sofia History Museum. The spring water is hot – 33C – and requires cooling before drinking. So if you are desperate for a cooling drink on a summer day this is not the place to go. Instead you can buy a bottle of Bankya or Gorna Banya mineral water, both sourced from springs around Sofia.
