The 2nd century thermae (warm baths) are the main part of the remains of the largest Roman public building in Bulgaria. During this century a large part of this historical site has been revealed by the archaeologists.  Thus a very thorough and exact description of this important landmark has been achieved, though some parts of the building remain hidden under the streets nearby. Coming across an extensive ancient building amidst the streets and houses of a modern city is not unusual in Bulgaria, but it is always a delight.
