Not used as pylons anymore:

The two pylons, built in 1955, are both 232-metre-high (761 ft) free-standing steel towers. Each stands on an 8-metre-high (26 ft) cross-shaped base and is equipped with a crossbar that carries four conductors at a height of 212 metres (696 ft), and another V-shaped structure at the top which carries two additional conductors in addition to ground wires. In contrast to more conventional pylon design, the corners of the pylons are arranged diagonally along the direction of the course of the line. The pylons of Messina were the model for the Elbe Crossing 1 in Germany and were, until the completion of Elbe Crossing 2, the tallest pylons in the world.
