The 1998 explorations confirmed the existence of Roman spa. On that occasion, the remains of a Roman architectural complex with a special heating system, as well as many ordinary and hypocaust bricks, pottery and glass was discovered. In 2008, the conservation of discovered remains of the Roman public bath was initiated.
Heating of water and rooms in spas was carried out by a special heating system (hipocaustum). Heated air flowed through the channels in the walls to certain places in the pools and thus heated the water.
The rooms were heated by warm air circulating through special coatings in the walls and through the cavities in the floors.
Spas are regarded as fully Roman heritage and have an important role in the lives of the Romans. Swimming itselfwas a long and complex procedure that was done in a group, the price was minimal, and the spas were available to everyone. Roman public baths were not only used to maintain physical hygiene, but they also had rooms in which visitors could practice and have fun.

The scientists claim that the spas were the precursor to the modern Wellness and Fittnes Centers, which proves that the tradition of nourishing the body and spirit in Laktašihas acenturies-long tradition.
