  We report the discovery of statistically significant spatial structures in
the projected two-dimensional distributions of the Globular Cluster (GC)
systems of 10 among the brightest galaxies in the Fornax Cluster. We use a
catalog of GCs extracted from the Hubble Space Telescope (HST) Advanced Camera
for Surveys (ACS) Fornax Cluster Survey (ACSFCS) imaging data. We characterize
the size, shape and location relative to the host galaxies of the GC structures
and suggest a classification based on their morphology and location that is
suggestive of different formation mechanisms. We also investigate the GC
structures in the context of the positions of their host galaxies relative to
the general spatial distributions of galaxies and intra-cluster globular
clusters in the Fornax Cluster. We finally estimate the dynamical masses of the
progenitors of some GC structures, under the assumption that they are the
relics of past accretion events of satellite galaxies by their hosts.
