Macau packs centuries of East-meets-West history into a compact, walkable core, and these picks make the most of a short visit. The Ruins of St. Paul's, the stone facade of a 17th-century church destroyed by fire, remains the citys defining landmark and a must for first-time visitors. Nearby, Macau Tower offers sweeping views over the Pearl River Delta and skyline, a useful contrast to the old town below. Return after dark to see the Ruins of St. Paul's at Night, when dramatic lighting transforms the facade into something even more striking. Together these stops cover Macaus colonial past and modern skyline in one efficient loop.
