The Kunstmuseum Stuttgart is hard to miss—by day, it’s a sleek glass cube reflecting the city; by night, its illuminated limestone core glows from within. The museum holds around 5,000 square metres of exhibition space, much of it tucked beneath the square in repurposed tunnels. It’s home to the world’s largest collection of works by Otto Dix, including his famous triptych Großstadt. The collection also includes pieces by Adolf Hölzel, Willi Baumeister, and other key figures in modern and contemporary German art.

Over a century old, the Speicherstadt is the world's largest integrated complex of warehouses. Visitors to Hamburg will discover a picturesque setting of Wilhelmine era Gothic architecture rendered in red brick, featuring unusual gables and towers. Precious commodities are stored at controlled temperatures behind the massive walls: coffee, tea, cocoa, spices, tobacco, and the world's largest collection of Oriental rugs. If you're pressed for time or wish to give your feet a rest after exploring the city, consider taking a one-hour evening boat tour. The Speicherstadt looks particularly enchanting at sunset.

Perched atop Württemberg Hill, the Sepulchral Chapel (Grabkapelle) was built by King Wilhelm I in the early 19th century as a tribute to his late wife, Katharina. Designed by court architect Giovanni Salucci, the neoclassical structure features a domed rotunda and houses the tombs of the royal couple and their daughter. The chapel is surrounded by vineyards and offers panoramic views over the Neckar Valley and Stuttgart.
