Completed in 1956, the Stuttgart TV Tower was the world’s first television tower built with reinforced concrete and remains a model for others globally. Standing at 216.61 metres, it offers stunning views from its observation decks and is home to a rotating restaurant and café.

Built in the early 1400s, around the same time as the Forbidden City, the Temple of Heaven was where emperors prayed for good harvests. The vast park contains several ceremonial buildings, the most striking being the Hall of Prayer for Good Harvests with its blue-tiled roof and intricate wooden ceiling. The original hall was destroyed by lightning in 1889 but rebuilt soon after. Other highlights include the Hall of Abstinence, where emperors fasted before rituals, and the Circular Mound Altar — a three-tiered marble platform symbolising heaven itself. Today, the park is as much about everyday life as it is about history: locals gather here in the mornings for tai chi, dancing, and music.

The Temple of Hephaestus is a well-preserved ancient Greek temple built in 450 BC, dedicated to the God Hephaestus, the protector of blacksmiths, craftsmen, artisans, sculptors, metals, metallurgy, fire and volcanoes. This may be one of the most well-preserved temples, not only in Greece, but in all of Europe.
