  Birth environments of young stars have strong imprints on the star itself and
their surroundings. We present a detailed analysis of the wealthy circumstellar
environment around the young Herbig Ae/Be star TCrA. Our aim is to understand
the nature of the stellar system and the extended circumstellar structures as
seen in scattered light images. We conduct our analysis combining archival
data, and new adaptive optics high-contrast and high-resolution images. The
scattered light images reveal the presence of a complex environment composed of
a bright forward scattering rim of the disk's surface that is seen at very high
inclination, a dark lane of the disk midplane, bipolar outflows, and streamer
features likely tracing infalling material from the surrounding birth cloud
onto the disk. The analysis of the light curve suggests the star is a binary
with a period of 29.6yrs. The comparison of the scattered light images with
ALMA continuum and 12CO line emission shows the disk is in keplerian rotation,
with the northern side of the outflowing material receding, while the southern
side approaching the observer. The disk is itself seen edge-on. The direction
of the outflows seen in scattered light is in agreement with the direction of
the more distant molecular hydrogen emission-line objects (MHOs) associated to
the star. Modeling of the SED using a radiative transfer scheme well agrees
with the proposed configuration, as well as the hydrodynamical simulation
performed using a Smoothed Particle Hydrodynamics code. We find evidence of
streamers of accreting material around TCrA. These streamers connect the
filament along which TCrA is forming with the outer parts of the disk,
suggesting that the strong misalignment between the inner and outer disk is due
to a change in the direction of the angular momentum of the material accreting
on the disk during the late phase of star formation.
