This archaeological landmark is the third largest Roman ruins found in Europe, and of course the largest in Bulgaria. These baths were built in the second century AD, and in those days the Romans enjoyed bathing in them with cold water, lukewarm water or hot water. Noting that the remains available for a visit are only a small complex compared to the original size of the baths. In addition, the location of these ruins is picturesque, so that behind them you will find modern residential buildings that add a comparison between the past and the present.
