Tolkien Gateway  Cerin Amroth  Atop Cerin Amroth by Anke Eißmann
Cerin Amroth was a mound in the heart of the ancient land of
Lothlórien on which grew two rings of trees and a great tree
with a white flet.[1]  The hill was originally piled after the
first millennium of the Third Age to be used as an outlook post
for the growing shadow of Dol Guldur. Amroth, the king of
Lórien, later built a house on the flet to use as a home and the
hill became named after him.[2] However his house was not
present centuries later, and the hill was covered with elanor
and niphredil.[3]  It was here that Aragorn and Arwen betrothed
centuries later, and where Arwen surrendered her life[4] in
Fo.A. 121.[5]  [edit] Etymology  Cerin Amroth is a Sindarin name
meaning "Amroth's Mound", consisting of cerin + Amroth.[6]
