It is a defense tower to be used as an outpost.
That explains the rough building style. It was build by the soldiers in short time to setup a defense against the goblins and upcoming minotaurs.

Personally it reminds me of guarding towers of the roman empire, see http://en.wikipedia.org/wiki/Limes_Germanicus
