The tripto catalogue lists 65 buildings and landmarks: city gates, bridges, town halls, concert halls and modern architecture. You can see many of them on a city walk without a ticket.
The Brandenburg Gate on Pariser Platz is open around the clock and free. Just a few steps away is the Reichstag Building with Norman Foster's walk-in glass dome – the view is free but requires advance registration. In Hamburg, the Elbphilharmonie Plaza at a height of 37 metres has charged entry since October 2026 (€5), while the Speicherstadt, the largest historic warehouse district in the world and a UNESCO World Heritage Site, remains free. The Porta Nigra in Trier is a Roman city gate from around 170 AD, and the Krämerbrücke in Erfurt carries 32 inhabited half-timbered houses over the Gera river.
Most landmarks in the catalogue are in Saxony (around 10, for example in Dresden and Leipzig), Hamburg (close to 10) and Berlin (a handful). Hamburg and Berlin lead among cities.
In practice: 45 minutes to two hours is usually enough for a landmark. About a third of the places in this category are marked as free in the catalogue, including the Brandenburg Gate, the Speicherstadt, the Stone Bridge and the Krämerbrücke. Interiors and tours charge, such as the Porta Nigra (€6) or a tour of the Semperoper (€16). Book the Reichstag dome and the Elbphilharmonie online in advance.
