Hagia Sophia (Ayasofya)

Worth it if you're into architecture or history—45,000+ people don't rate it 4.8 for nothing. Go early morning to dodge crowds, skip the pricier guided tours unless you genuinely want context, and budget for entry; the sheer scale and light alone justify the trip if you're spending time in Istanbul anyway.
