Keywords: function fields | finite fields | ramification | genus | recursive towers | dual towers

We introduce the notion of the dual tower of a recursive tower of function fields over a finite field.We relate the ramification set of the tower with the one of the dual tower , for the case of good asymptotic behaviour of the genus.
