Embark on a journey back in time to the medieval villages nestled within the county of Essex and delve into the rich history of Cambridge, tracing back to the Roman era. Your first stop is Thaxted, a charming village cradled in the valley of the River Chelmer. This historic gem boasts over a millennium's worth of history and industry, offering plenty for you to uncover. Stroll through the tranquil streets, admire the thatched cottages, and gaze upon the renowned church spire. You might even venture towards John Webb's Windmill on the town's outskirts, the last standing windmill that stands as a tribute to the region's traditional wool industries.

Once you've fully explored Thaxted, your journey continues to the illustrious city of Cambridge. Here, you can explore the esteemed university and its iconic college buildings. But there's more than just academia to this city; it also offers popular museums, historic churches, bustling market squares, and the opportunity to go punting along the peaceful River Cam. For lunch, choose from an abundance of pubs, cafes, and tea rooms.

Your day concludes with a visit to Saffron Walden, a medieval market town known for its timber-framed houses. If your visit falls on a Tuesday or Saturday, you'll have the chance to browse the local market for regional produce and gifts. After some refreshments and a thorough exploration of this world-renowned market, you'll return to London in the early evening.
