Aquincumi Museum, Szentendre

Budapest is so full of history that it's easy to forget the Romans were here two thousand years ago. Their settlement was known as Aquincum, and the Aquincum museum brings its' history to life. A large outdoor area full of ruins gives us a clear picture of building layouts and patterns, while the museum itself houses some real treasures, including the world-famous portable water organ. This musical device clearly shows just how advanced the Romans actually were.
