Abstract: We obtain the action for the chiral Carroll string moving in a curved string-Carroll target spacetime from a Carroll expansion, in powers of the speed of light $c$, of the action for the relativistic closed bosonic string. Applying this setup to a classical closed bosonic string approaching the $4$-dimensional Schwarzschild black hole, we study the dynamics of the string when it behaves as a chiral Carroll string with the near-horizon string-Carroll expanded geometry as the target spacetime. We find that the chiral Carroll string can have either left-moving or right-moving fluctuations on the horizon, while exhibiting a non-trivial motion in the Rindler spacetime which depends on these horizon fluctuations.
