  Globular cluster are believed to boost the rate of compact binary mergers
which may launch a certain type of cosmological gamma-ray bursts (GRBs).
Therefore globular clusters appear to be potential sites to search for remnants
of such GRBs. The very-high-energy (VHE) gamma-ray source HESS J1747-248
recently discovered in the direction of the Galactic globular cluster Terzan 5
is investigated for being a GRB remnant. Signatures created by the
ultra-relativistic outflow, the sub-relativistic ejecta and the ionizing
radiation of a short GRB are estimated for an expected age of such a remnant of
t > 10^4 years. The kinetic energy of a short GRB could roughly be adequate to
power the VHE source in a hadronic scenario. The age of the proposed remnant
estimated from its extension possibly agrees with the occurrence of such events
in the Galaxy. Sub-relativistic merger ejecta could shock-heat the ambient
medium. Further VHE observations can probe the presence of a break towards
lower energies expected for particle acceleration in ultra-relativistic shocks.
Deep X-ray observations would have the potential to examine the presence of
thermal plasma heated by the sub-relativistic ejecta. The identification of a
GRB remnant in our own Galaxy may also help to explore the effect of such a
highly energetic event on the Earth.
