1. A mast section for a wind turbine having a longitudinal center axis extending in a longitudinal direction and comprising a wall having an inner surface and an outer surface, the mast section comprising:
at least two tubular mast elements stacked in the longitudinal direction and arranged edge to edge at a joining plane, each tubular mast element comprising at least two wall segments, connected to each other by segment connectors extending along longitudinal edges of the wall segments,
element connectors each extending across the at least two tubular mast elements and connecting the tubular mast elements to each other,
the element connectors being arranged on one of the inner surface and the outer surface of the wall of the mast section and the segment connectors being arranged on the other of the inner surface and the outer surface of the wall of the mast section and each element connector extending at least partly opposite at least one of the segment connectors in a radial direction of the mast section so that the each element connector and the opposite at least one segment connector at least partly overlap over an overlapping height.
