Many explicit recursive towers were described since about 20 years, unfortunately without any hint for there discovery. We will give in this talk some necessary conditions for a recursive tower to be good. We will also prove a nice property on the number of points of given degree at high level of the towers. The main tools will be intersection theory on surfaces and graph theory. This is a joint work together with Emmanuel Hallouin.
