Summertime by Jackson Pollock

You'll find Pollock's Summertime on a Winchester street corner, which isn't where you'd expect to stumble across one of America's most famous abstract expressionists. It's a bollard - yes, a proper street post - decorated with a reproduction of the 1948 painting, turning functional civic infrastructure into something worth a double-take.

The work itself is unmissable: a riot of dripped and splattered paint in blues, yellows, and blacks that somehow coheres into something electrifying. It's the kind of piece that makes you stand there wondering how the artist actually created it, and why this particular stretch of Winchester warranted such a striking cultural intervention.

This isn't a destination in itself - you won't spend hours here. But if you're already in Winchester wandering the cathedral quarter or poking round the high street, it's absolutely worth locating. It takes two minutes to appreciate, and it's free. History enthusiasts and modern art fans will get a kick out of seeing Pollock displayed so unexpectedly on a pedestrian thoroughfare rather than museum walls.

If you're staying at one of the local caravan parks - Hookpit Farm (3.5 miles away) is particularly well-rated - pop into town for a morning walk and make it part of your route. Winchester's compact enough that you can string together several cultural moments without much effort. The bollard fits perfectly into a half-day exploring the city's mix of medieval and contemporary art.
