  NGC 6744 is the nearest and brightest south-hemisphere galaxy with a
morphological type similar to that of the Milky Way. Using data obtained with
the Integral Field Unit of the Gemini South Multi-Object Spectrograph, we found
that this galaxy has a nucleus with LINER (Low Ionization Nuclear Emission Line
Region) surrounded by three line emitting regions. The analysis of the Hubble
Space Telescope archival images revealed that the nucleus is associated with a
blue compact source, probably corresponding to the active galactic nucleus
(AGN). The circumnuclear emission seems to be part of the extended narrow line
region of the AGN. One of these regions, located $\sim$1" southeast of the
nucleus, seems to be associated with the ionization cone of the AGN. The other
two regions are located $\sim$1" south and $\sim$0.6" northeast of the nucleus
and are not aligned with the gaseous rotating disk. Spectral synthesis shows
evidence that this galaxy may have gone through a merger about one billion
years ago. On the basis of the kinematic behavior, we found a gaseous rotating
disk, not co-aligned with the stellar disk. Given the relative degree of
ionization and luminosities of the nuclear and circumnuclear regions, we
suggest that the AGN was more luminous in the past and that the current
circumnuclear emissions are echoes of that phase.
