Abstract: We study wormhole solutions obtained via applying dualities and complexifications to the vacuum Weyl metrics generated by massive rods and by point masses. The most interesting finding are wormholes with locally flat geometry supported by rings of negative energy. Such wormholes can also be obtained by taking to zero the mass of the Kerr spacetime.
