The major contribution of Roman architecture are the hot springs (true Roman construction), but we also have the use of the arch, which is another key feature of its architecture.

The baths were a place to bathe, but also to spend time (place to walk, talk with friends or do physical exercises). All access to the baths could pay a small fee. guarding the environment is a delicate decoration where media is not spared, filling the rooms with wonderful frescoes, mosaics and statues. We have different stays within the Roman baths, such as: * Apodyterium: costume-wardrobe / / * Lecture: central courtyard that opened all the other rooms and exercise could be practiced / / * Frigidarium: living cold water / / * Tepidarium: warm water room / / * Destrictarium: where the skin is cleaned (about a pond) / / * Laconicum: where steam is performed / / * Caldarium: hot room / / * Unctorium: access room is next to the bathroom / / * Natatio: cold pool may be within or outside frigidarium / / much fuel was needed to develop this much water bath system. Water resources were brought through the network of Roman aqueducts that every city had. The interior of the rooms and hot water pools was performed by hypocaustum system. The system is based on distribution through tunnels and tubes of hot water and steam that ran beneath the floors of the rooms and pools, and was fed by a series of furnaces were in the basement. And now a video to clarify these concepts:
