  We investigate Abydos, the final landing site of the Philae lander after its
eventful landing from the Rosetta spacecraft on comet 67P/Churyumov-Gerasimenko
on 12 November 2014. Over 1000 OSIRIS level 3B images were analysed, which
cover the August 2014 to September 2016 timeframe, with spatial resolution
ranging from 7.6 m/px to approximately 0.06 m/px. We found that the Abydos site
is as dark as the global 67P nucleus and spectrally red, with an average albedo
of 6.5% at 649 nm and a spectral slope value of about 17%/(100 nm) at
50$^\circ$ phase angle. Similar to the whole nucleus, the Abydos site also
shows phase reddening but with lower coefficients than other regions of the
comet which may imply a thinner cover of microscopically rough regolith
compared to other areas. Seasonal variations, as already noticed for the whole
nucleus, were also observed. We identified some potential morphological changes
near the landing site implying a total mass loss of 4.7-7.0$\times$10$^5$ kg.
Small spots ranging from 0.1 m$^2$ to 27 m$^2$ were observed close to Abydos
before and after perihelion. Their estimated water ice abundance reaches 30-40%
locally, indicating fresh exposures of volatiles. Their lifetime ranges from a
few hours up to three months for two pre-perihelion spots. The Abydos
surroundings showed low level of cometary activity compared to other regions of
the nucleus. Only a few jets are reported originating nearby Abydos, including
a bright outburst that lasted for about one hour.
