As you had already secretly longed for in your latent heart, Diagon Alley is now explorable in Google Street View, in all 360 degrees of glory (more accurately, it's the set of Diagon Alley from the Warner Bros. studio tour in London, but let's not get nitpicky because that will ruin the magic). Go ahead forth and virtually explore — but don't take a wrong turn or you'll end up in Knockturn Alley with a spotty goblin mouth-breathing on you.
