Corral/1.03

Barbarian
The Corral is a cheap and average sized building that allows for the production of the Barbarian cavalry units, as well as powering them up with a total of four researches. However, it's not just their cavalry units that are affected by the researches it offers, the Pegasus is also affected, largely improving its already decent traits to intimidating levels. The Corral may not actually produce any units, but by offering four researches that affect three different units, allowing for the production of two cavalry units, which includes one of the Barbarians strongest units, the Corral can do a lot for the Barbarian race and shouldn't be discarded based on its limited production value or the usual ineffectiveness of cavalry units in general - as upgraded Riders become faster than Lizard Riders, making their speed actually noticeably different to standard infantry, and Pegasi and Warlords become powerful threats.
