Early Duns had near vertical ramparts constructed of stone laced with timber, and where this was set on fire (accidentally or on purpose) it forms the vitrified forts where stones have been partly melted, an effect that is still clearly visible.

As such it was widely and normally constructed upon a height, and almost always had some sort of an acropolis built at the highest point within its towered walls. In the archeological record of the Iberian Peninsula, the remnants of as many as a thousand fortified places identifiable as Castros can be found in modern day Portugal alone.</History>

     <History>The Akropolis was usually a fortified citadel in the upper part of the city. The Athenian Akropolis was renowned for its marvellous temples, among which was the Parthenon, while the Acro-Corinthus was highly prized by the Macedonians for its strategic location and good defences. Fortresses (also called a "phrourion") were also built to guard passes and atop hills in order to command plains and valleys below.</History>
