Treble Clef by Joseph Albers

You'll spot Joseph Albers' Treble Clef bollard somewhere in Winchester's streets - a proper piece of public art that doesn't demand you pay entrance fees or book a timeslot. It's exactly the sort of thing that makes wandering a market town worthwhile: you're just going about your day and suddenly there's a work by one of the 20th century's most influential abstract artists blocking traffic rather quietly.

Albers was obsessed with colour and form, and this bollard - yes, a functional street object - shows his hand. It's not going to stop you for hours, but it's the reason to explore Winchester's town centre properly instead of just hitting the high street. History types will appreciate the low-key artfulness of it all; families won't feel they've wasted time if they stumble across it while hunting for lunch.

From the caravan parks dotted around Winchester - Hookpit Farm and Holden Farm are both decent spots with strong ratings - you're only a few minutes' drive into town. The Morn Hill site sits closest at 2.5 miles if you want minimal faffing about. Give yourself an afternoon to wander Winchester's grid of streets and actually notice the public art scattered about rather than rushing through. It costs nothing, takes minimal time, but reveals something about how art sits in everyday life rather than locked behind gallery walls. That's worth the trip from your pitch.
