Academy

Prerequisites: Barracks level 3, Main Building level 3, Travian Version 2.5 or higher

In the academy new unit types can be developed. By increasing its level you can order the research of better units.
Some troops also require other buildings in order to be researched. For example, the Imperian (Roman) needs an Academy level 5 and a Blacksmith level 1. Look at the troops page to view the prerequisites.
