Sõjamäe (Sõjamägi) 
Tricky, literally War Hill, its meaning could range from Soldiers’ Knoll, Martial Mountain, Battle Bump, to Bruise. Military vantage point / observation post sound good too. Most faithful, however, is Battle Hill (see Mäe for discussion). Comes in all sizes: Väike (Small), Kesk (Medium), Suur (Large), and, forgive the mixed metaphors, Vanilla. Named after manor house (see Mõisa) itself named after what is believed to be the site of a battle following the Jüriöö Ülestõus (St. George’s Night Uprising) of 1343-04-23 where the Teutonic Order killed some 3000 Estonians in an orgy of attrition and revenge.
