Völklinger Hütte, one of the world's largest iron works spreading across six hectares, was established in 1873, and has remained remarkably intact during its operation spanning the next hundred years. Today, as a UNESCO World Heritage Site, it functions as a museum and science centre, offering interesting insight into the industry's history.

Conceived by Henry Ford II, the Renaissance Center, commonly known as the RenCen, is a striking complex of seven interconnected skyscrapers designed to boost Detroit’s economy. The central tower, the tallest and most iconic in the city, stands as a symbol of modern Detroit and offers stunning views from its observation deck. Home to General Motors, this architectural marvel is a must-see, showcasing both the city’s growth and its future.

This is Porto Santo’s most popular walk, though it rarely feels crowded, especially if you go first thing in the morning. The well-marked PR1 trail is around 5 km return and threads through the island’s northeastern hills, crossing a protected Natura 2000 area where you can spot native plants, wildflowers, and seabirds. The route is moderately challenging, with some steady climbs, but nothing too demanding for anyone used to hill walking. The reward comes at the viewpoints. Terra Chã looks out over rugged cliffs and deep blue water, while Pico Branco, the island’s second-highest point, offers wide 360-degree views across Porto Santo and the Atlantic beyond. The whole hike typically takes under three hours at an easy, unhurried pace, and at the top, you'll find a few picnic areas if you want to recharge before heading back.
