Fortress (Warcraft II)

As the military and economic center of the largest Orc cities, the Fortress can hold and process all the gold and lumber that the Peons can be made to harvest. Protected by obsidian spires shaped from the earth itself, the Fortress is all but impervious to the attacks of the feeble Human forces. Constructed by Orcish leaders attaining arrant mastery both on and off the field of battle, the Fortress serves as a proclamation to the Alliance of the inevitable triumph of the Orcish Horde.

Information

 * A Fortress makes your gold mining more efficient: whenever a Peon delivers gold, 120 gold will be added to your stockpile instead of 100.
