  We consider circular motion in the NUT (Newman-Unti-Tamburino) space-time.
Among other things, we determine the location of circular time-like geodesic
orbits, in particular of the innermost stable circular orbit (ISCO) and of the
marginally bound circular orbit. Moreover, we discuss the von Zeipel cylinders
with respect to the stationary observers and with respect to the Zero Angular
Momentum Observers (ZAMOs). We also investigate the relation of von Zeipel
cylinders to inertial forces, in particular in the ultra-relativistic limit.
Finally, we generalise the construction of thick accretion tori ("Polish
doughnuts") which are well known on the Schwarzschild or Kerr background to the
case of the NUT metric. We argue that, in principle, a NUT source could be
distinguished from a Schwarzschild or Kerr source by observing the features of
circular matter flows in its neighbourhood.
