At the far western end of Portsdown is the town of Fareham. Along Pinks Hill, the southern approach road to
Fort Wallington (a Palmerston Fort), is the only example of an intact
anti-invasion pillbox left on Portsdown, since the destruction of the
one at Racecourse Lane.
It is a type FW3/25 (ARMCO) pillbox,
which was designed to be proof against rifle fire. It would typically
contain 4 infantry men armed with light automatics.
