International Garden Cities Institute

The International Garden Cities Institute sits just outside Baldock, documenting one of Britain's most ambitious urban planning movements. It's housed in a modest building that tells the story of how garden city ideals - mixing town and countryside living - took root across the globe from the early 1900s onwards.

You'll find archives, displays, and plans showing how towns like Letchworth and Welwyn Garden City were designed from scratch. The collection includes original drawings, photographs, and correspondence that genuinely illustrates how radical this thinking was at the time. It's proper niche stuff, and not a place where you'll spend half a day, but if you're interested in urban design, social history, or how Britain's new towns came about, it's absolutely worth an hour of your time.

Really suits architecture enthusiasts and anyone curious about how places are built rather than just grown. Families with young kids will likely find it dry unless they're already keen on that sort of thing. The institute sits well within reach of the caravan parks scattered around Baldock - Radwell Lake and Jacks Hill are barely two miles away - making it an easy afternoon visit if you're based in the area for a longer stay.

Best to call ahead or check their website for opening times and whether admission is charged, as details aren't widely listed. It's the sort of place that rewards a bit of planning rather than a casual drop-in.
