In Skäftekärr, close to Böda in northern Öland, lies an Iron Age village with around 20 well-preserved stone house foundations spread across 10 farms dating from 300–700 AD. At the heart of the Iron Age village are the remains of a chieftain's estate, comprising four house foundations. Adjacent to this historic site, the "new Iron Age landscape" includes a reconstructed version of one of these typical houses and the charred remains of an earlier reconstruction. The park is also home to an impressive collection of approximately 140 different species of trees and shrubs, forming an arboretum. An eco-park center with information about the Böda Eco-park is available on-site, along with Skäftekärr café, hotel, and conference, housed in the majestic main building. For the little ones, a popular obstacle course adds to the day's adventure.

This tastefully restored Victorian waterworks facility offers a unique opportunity to learn about the city's industrial history and about innovations in water and renewable energy today. The Lifetime Lab is an award-winning visitor centre and a must-visit for budding scientists.

The Yuejiang Tower in Nanjing boasts a unique history, having achieved fame centuries before its actual construction. In 1374, the first Emperor of the Ming Dynasty envisioned a tower by the Yangtze River, naming it Yuejiang (literally meaning "overlooking the river"). He commissioned authors across the country to write articles praising the magnificent tower, even though it was not yet built. One of these articles became a classic, but the tower's construction was not started until 2000. The reputation of the Yuejiang Tower preceded its actual existence by 650 years.
