In this thesis, we study a Drinfeld modular interpretation due to Elkies of an asymptotically optimal tower that was constructed by Bezerra and Garcia. We explain what an asymptotically optimal tower over a finite field Fq is and give the de nition of the asymptotically optimal tower given by Bezerra and Garcia. We give some basic facts about Drinfeld modules. Additionally, we present the analytical theory of Drinfeld modules using lattices and exponential functions to better understand the analogy with the classical theory. We exhibit the Drinfeld modular curves that give the tower of Bezerra and Garcia. Hence we see a Drinfeld modular interpretation of this tower.
