When Bing's homepage showed the windmills of Kinderdijk, the accompanying quiz became one of its most-searched, proof that a single landmark can carry a whole round. The facts are wonderfully specific, which makes this quiz easy to master.

What Kinderdijk is

Kinderdijk is a village in the Netherlands, in South Holland near Rotterdam, home to a famous group of 19 historic windmills built around 1740. It's among the largest surviving concentrations of old windmills in the country and a UNESCO World Heritage Site since 1997.

Why the mills exist

They weren't grinding grain, Kinderdijk's mills were built to pump water and drain the low-lying polder land, much of which sits below sea level. That water-management story is the Netherlands in miniature, and 'what were the mills built for' is the core question.

Details Bing has asked

How many mills stand at Kinderdijk (19), which country they're in (the Netherlands), roughly when they were built (around 1740), and their UNESCO listing (1997). Broader Dutch questions, tulips, dikes, why so much land lies below sea level, ride along naturally.

Landmark-quiz strategy

Single-landmark quizzes reward the caption: it names the site outright. From there, the site's official or UNESCO page confirms any number the question probes.
