The Westmarch of the Shire was land that lay between the Far Downs and the Tower Hills in Eriador, west of and originally outside of the Shire. The only known town in this new district was Undertowers.
At the request of Mayor Samwise, Thain Peregrin I made Fastred of Greenholm the first Warden of Westmarch in S.R. 1462. Fastred and Elanor Gardner moved to Undertowers; many other hobbits migrated to the Westmarch.
