This London bollard is outside the site of a former police station, near Victoria station. It's on a side road and I bet most people never see it. More below...

This London bollard is outside the site of Gerald Road Police Station (1846-1993), SW1. It's near the junction with Elizabeth Street. (See location map.)

I had never noticed this unusual bollard but discovered it on the Bollards of London blog. Yes, a blog dedicated to these stubby street posts!
