Arnor

All that is gold does not glitter,

Not all those who wander are lost;

The old that is strong does not wither,

Deep roots are not reached by the frost.

From the ashes a fire shall be woken,

A light from the shadows shall spring;

Renewed shall be blade that was broken,

The crownless again shall be king.

Whether the Last Bridge was built by the Arnorians or previous inhabitants of Eriador as far back as the First Age is unknown. The bridge fell under the domain of Arnor and then Rhudaur who maintained it. The Last Bridge marked the only crossing point over the Mitheithel (River Hoarwell) south of the Ettenmoors.

After Annúminas was abandoned, Fornost Erain became the capital of Arnor and then Arthedain after the split. The name itself means "Northern Fortress of the Kings." It was destroyed in 1974 of the Third Age during the war against Angmar, leaving the city a mass ruin. In the language of men it was known as Norbury with the nickname Deadman's Dike as it was believed to be haunted and avoided at all costs. Only the Rangers of the North were ever seen entering the city and none knew of what they did within.

Founded in the year 3320 of the Second Age of the Sun by Elendil the Númenórean, Annúminas was the capital of the Northern Kingdom of the Dúnedain -- Arnor. By 861 of the Third Age, the population of Annúminas had dwindled and soon the city was abandoned. Fornost replaced the city as capital and major city. The ravages of time have caused Nenuial to erode the lakewall of Annúminas, causing major flooding and giving it the name - The Sunken City.

From the start of its existence, Rhudaur was unfriendly towards the two other successor states, and took part in a bitter conflict with Cardolan over the tower of Amon Sûl and the Palantír associated with the tower.

The last Kings of Rhudaur were not of Númenórean blood, but were descended of Hill-men in service of Angmar. Under their rule the land became a vassal of Angmar, and thus enemies of Cardolan and Arthedain. - Tolkiengateway.net
