Stretching for 74 miles across the hills and
valleys of Northern England, Hadrian's Wall was
erected by Roman soldiers to mark the Northern
boundary of their empire. Well over a thousand
years after the Roman Empire has collapsed, this
edifice still stands in mute testament to its
builders, a fascinating structure historians and
archeologists study to this day. Built of stone
and mortar by Roman soldiers, it is the most
significant Roman ruin in England. In this
episode of the Modern Marvels series, the
construction of this architectural wonder is
investigated by leading scholars of the Roman
Empire. This program reveals how Hadrian's Wall
was actually used as a gateway into the empire
rather than purely as a defensive barrier, and
how it has managed to survive for nearly 2,000
years. This documentary offers valuable insights
into Roman innovations in architecture, the
techniques of archeological discovery, and the
history of the Roman Empire.
