The Ruins of Saint Paul's, a UNESCO World Heritage Site in Macau, are the iconic facade of a 17th-century church destroyed by fire. Accessibility is generally good, though the area can get crowded. Visiting solo is perfectly feasible, allowing for flexible exploration, though guided tours offer deeper historical context. There are no specific seasonal restrictions, but be prepared for hot and humid weather, especially during summer. The visit is free, although there are costs associated with travel to and from the site and any purchases made in the surrounding area. A typical visit lasts 1-2 hours.
