The remains of Roman age   
    The recorded history of the area begins at the time of Roman Empire. At the beginning of our era the nearby Danube River was the "limes", the border of the empire throughout four centuries. Brigetio (the later Szőny), which was bulit on a militarily important location, got the water that was essential for the Roman baths from Tata's springs. Mátyás Bél, an excellent scientist of the 18th century, gave an interesting description of the water-conduit between Tata and Szőny, the best part of which was built as an aqueduct.
    The surrounding area of the springs proved to be too little to provide for a whole settlement, but the countryside offered good opportuníty for building "villas". The veterans, a great number of ehom came from the remote corners of the empire, even from other continents, in many cases chose place not far from their former units to setle down after their service had expired. Then, near the springs, they would set votive altar-stones to Aesculap, Hygieia or simply to the nymph of the spring.
