Encircling the heart of Xi'an, the Ancient City Wall stretches almost 12 kilometres and stands as one of China’s best-preserved city walls. Built over 600 years ago during the Ming Dynasty, this massive structure invites exploration by foot or bike, with the entire loop offering a unique way to see Xi'an from above. Walking or cycling along the wall, you’ll pass traditional watchtowers and gates that once guarded the city’s entrances.

The best way to cool down is by plunging into the clear, refreshing water. All the better if you don't even need to leave the city centre to do it. Zurich offers sandy beaches and grassy area to sunbathe, diving towers, panoramic views of the Alps. Read a book in the shade of the trees, swim in the lake or the river — Zürich has a bathing spot for every taste. The public bathing traditions on Zürich stem from the Romans. Today, you can find more than 15 open-air baths. Many locations are equipped with showers and changing room.

In addition to the Rotonda, this is one of the two most characteristic monuments in town. The Galerius arch is situated close to the eastern city wall, a short distance from the Kassandreotiki gate. The 4th-century AD Roman emperor Galerius commissioned both structures to show off his power. A road used to run through the arch, past the Rotunda and on to the palace to the southwest. The arch is composed of a masonry core faced with marble sculptural panels celebrating a victory over the seventh emperor in the Sassanid Persian Empire. About two-thirds of the arch is preserved. Colloquially, the monument in known as Kamara, that's Greek for 'arch'.
