Tower for a wind power station

A tower (40) to support a wind-driven power-plant comprising an equipment nacelle (30) affixed to the tower (40) and a rotor (20) resting on the equipment nacelle in a manner to be rotatable about a substantially horizontal axis, said rotor being fitted with at least one rotor blade (22), said tower comprising an upper, tubular tower segment (46) which is connected in a transition zone to a lower tower segment (41) in the form of a lattice tower (42), said lattice tower comprising at least three corner posts (43) wherein the upper tower segment (46) constitutes at least one sixth of the entire tower, and wherein the cross-section of the lower tower segment (41) underneath the transition zone is larger than the cross-section of the upper tower segment (46), and in that the transition zone is designed in a manner that the cross-section of the lower tower segment is matched in a force-optimized manner to the cross-section of the upper tower segment.
