Óbuda is the oldest part of Budapest, "Ó" meaning old in Hungarian. Before the three parts of Budapest (namely Buda, Pest and Óbuda) were united in 1873, it used to be a small town with lovely baroque buildings built on the ruins of an old Roman settlement called Aquincum. Today, it preserves this atmosphere with its cobble stone streets and buildings renovated to resemble their original appearance. The remnants of the Roman settlement can be found here along with the Imre Varga Collection, Victor Vasarely Museum and a number of other smaller folklore museums.
