    Efficient construction of long AG--codes resulting from optimal towers of function fields is known to be difficult. In the following a tower which is both optimal and unramified, that is a tower in which all places are unramified after some level, is investigated in the hope that its simple ramification structure can be exploited in the construction of AG--codes. Results are mostly negative, but helps clarifying the difficulties in computing bases of Riemann--Roch spaces.
