  The orientation of the jet axis to the line of sight of the observer plays a
major role in explaining the phenomena observed from blazars and radio
galaxies. In the gamma-ray band, only a handful of radio galaxies have been
identified, all being located in the nearby Universe (z<0.5). Here we report
the identification of 4FGL J1435.5+2021, associated with TXS 1433+205, as a
Fanaroff-Riley type II (FR II) radio galaxy at a considerably higher redshift
of z=0.748, thereby making it the most distant gamma-ray detected radio galaxy
known as of now. The Very Large Array Sky Survey data at 3 GHz resolves the
source morphology into a bright core, a jet and two hotspots, with a total
end-to-end projected length between lobe extremities of ~170 kpc. The optical
and radio properties of this enigmatic object suggest it to be a
high-excitation FR II radio galaxy. The multi-wavelength behaviour of TXS
1433+205 is found to be similar to other gamma-ray detected FR II sources but
is at the high luminosity end. We suggest that the ongoing and upcoming
high-resolution radio surveys will lead to the identification of many more
high-redshift radio galaxies in the gamma-ray sky, thus allowing comprehensive
studies of misaligned relativistic jets.
