Until its union with Buda and Pest in 1872, Óbuda was a somewhat sleepy little town, and in spite of considerable rebuilding and modernization it has still managed to retain something of its former atmosphere. This old settlement, where evidence of prehistoric culture has been discovered and where shortly after the birth of Christ the Romans
founded their camp of Aquincum, was according to tradition the residence of the Hunnish king Attila in the 5th C.
Under the Árpáds the place experienced enormous prosperity. In the Middle Ages there was a palace of the Hungarian queens here; in the days of the Turkish occupation the little Danube town fell into complete decay, as a result of the increasing importance of the neighboring royal city of Buda. Not until the 17th C was life restored to the town by German-speaking settlers.
