Roman Utrecht
As said in the historic overview Utrecht originates from the Roman era. Under the Dom Square several remains of the Roman Fort and early middle age buildings are visible. The most important sit is the sublevel in "Cafe het Weeshuis" The "Orphan's house" pub, situated in the Northwst corner of the square. At the Dom Square a Roman border pile has been reconstructed and the locations of the south and east gates of the fort are marked.
Also in the new built city Leidserijn, many remains of the Roman border have been found, including one of the best preserved Roman Cargoships ever found! It is now under restauration but will be exhibited to the public when the restauration is done. Among other findings are: a watch tower, a harbour, remains of a village and roads (including the Limes).

The arches are from the Lofen Palace (10 - 11th century)

The witye stone pavement right are the fundaments of the Roman Fortress wall.

Here a remain of the Roman wall is visible in the cellars of the UCK (Utrecht school of art).
Plans exists to show the public these and other remains of the Romans by building an underground Roman Route to be finished in 2013. See http://www.domplein2013.nl
