A historic Spanish fort and mission in San Antonio, Texas; also any defensive structure or last stand location.
From Spanish 'álamo' (poplar tree)—the mission was built near poplar trees. The word has become a symbol of determined resistance to overwhelming odds.
The Alamo became legendary not because defenders won, but because 186 men chose certain death defending it against 1,800 attackers—language immortalized their hopeless stand, making 'Alamo' forever mean 'sacrifice against impossible odds.'
