ALDBURG
(Literally old fort)
The Mark's most ancient town lies south east of the capital city, Edoras, in the region known as The Folde. Due to the fact that the people of the Mark preserved their history in song rather than manuscript an exact date for Aldburg's founding is not forthcoming. It is assumed that the town and fortification, or hold, where founded by Eorl shortly after  the Rohirrim settled in Calenardhon, (III) 2510.

Aldburg remained the principal city of the Mark until the seat of the Kings was removed to Meduseld in Edoras.  The hold then became the home of the ancestors of Éomer & Éowyn
EDORAS (The Courts)

Tradition tells that the capital city of the Mark was founded by Eorl himself, but evidence to the contrary seems to disprove this legend. 

Eorl may have indeed decided to found a settlement here, but his home and hold were at Aldburg in the Folde east of Edoras. It seems likely that whilst he reigned over the Mark all matters of rule and governance would have taken place at Aldburg. 

What is known beyond doubt is that a large part of Meduseld, The Golden Hall, was constructed during the reign of Brego, son of Eorl. Upon the Hall's completion, in (III) 2569, Edoras became the royal and political seat of the Kingdom. The regional boundary of Edoras encompasses Meduseld, the city precincts and a broad swathe of land which surrounds them.

UPBOURN 

A settlement situated in Harrowdale (a deep valley cut by the Snowbourne River as it flows northwards from its source in the Ered Nimrais) some ten miles south east of Edoras.

UNDERHARROW 

A village found in Harrowdale which nestles below the mass of the Irensaga. Underharrow lies around 7 miles north east of the great pathway (the Stairs of the Hold) which climbs up to Dunharrow and its high plateau.


DUNHARROW

A fortified settlement situated at the southern end of Harrowdale. A steep pathway, lined by ancient statues of the Púkel-men, climbs up to a stepped plateau which lies in the shadow of the Dwimorberg (the Haunted Mountain). Dunharrow was chosen as the muster point of the Rohirrim before they rode to the aid of Gondor during the War of the Ring. 

Walda, 12th King of the Mark, was slain by orcs near Dunharrow in (III) 2851.


HELM'S DEEP

The great cleft and network of caverns situated in the foothills of the Ered Nimrais, north west of Edoras.  A mighty fortress, built by the men of Númenór in the Second Age, known to the Eorlingas as The Hornburg, guards the entrance to the valley. Helm's Deep has often been a place of refuge for the people of the Mark and was named after their mighty king, Helm Hammerhand, who withstood a siege by Wulf the Usurper and his Dunlendings during the Long Winter, (III) 2758-2759.
