Wiblingen Abbey - 4 Things to Know Before Visiting

Second tallest church in the world, after Sagrada Familia in Barcelona with a steeple measuring 161.5 metres (530 ft). Visitors can climb the 768 steps that lead to the top of the minster's spire. At 143 m (469 ft) it gives a panoramic view of Ulm in Baden-Württemberg and Neu-Ulm in Bavaria and, in clear weather, a vista of the Alps. The final stairwell to the top is a tall, spiraling staircase that has barely enough room for one person.

Literally translated to "Blue pot", it is a spring that serves as the source of the river Blau. It is a drain for the Blau cave system, originating from a funnel-like shape with a depth of 21 metres (69 ft). The water's peculiarly blue color, varying in intensity depending on weather and flow, is the result of physical properties of the nanoscale limestone particles densely distributed in the water.

Opened in 2002, it is 43.5 hectares (107 acres) in area, and it is one of the four most popular theme parks in Germany. The Miniland- one of the attractions in the park contains Lego reproductions of various German cities and rural landscapes.

Gothic Revival style fairy tale castle of Württemberg. The castle was inspired by the novel Lichtenstein (1826) by Wilhelm Hauff and was built in 1840–1842.

The castle rises above the river Danube on a towering chalk projection. It is about 200 meters (660 ft) long and up to 35 meters (115 ft) above the river.

World's oldest social housing complex still in use. Founded in 1516 by Jakob Fugger the Younger(a merchant, mining entrepreneur, and banker) as a place where the needy citizens of Augsburg could be housed.
