Morning light slides across cobbles as the group steps away from Market Square and into an architecture lesson written in stone and lawn. The river hums nearby, punts easing past willow shadows while the bell of King’s College Chapel threads through narrow streets. This three-hour private walking tour takes you through central Cambridge’s most recognisable scenes—Corpus Clock’s mechanical face, the Senate House, and the great colleges of Trinity, King’s, Gonville & Caius—while a local guide maps centuries of academic life onto buildings and back lanes.
