Konoha Hot Springs.
The Konoha Hot Springs is the public bath of Konohagakure, divided down the middle between the gender. Shinobi can use the baths as a training ground for basic chakra training. Using the the hot water as a form of motivation, the trainee is more focused in using their chakra to support themselves on the water. This is where Naruto is taken by Jiraiya to relax during his training. Like everything else in Konoha except for the Konoha Archive Library, it was destroyed when Deva Path used a massive Shinra Tensei to destroy the village.
