Amersfoort is a city and municipality in the province of Utrecht, Netherlands and is situated at the eastern edge of the Randstad. As of 1 January 2019, the municipality had a population of 156,286, making it the second-largest of the province and fifteenth-largest of the country. Amersfoort is also one of the largest Dutch railway junctions with its three stations—Amersfoort Centraal, Schothorst and Vathorst—due to its location on two of the Netherlands’ main east to west and north to south railway lines. The city was used during the 1928 Summer Olympics as a venue for the modern pentathlon events. Amersfoort marked its 750th anniversary as a city in 2009.

The nickname for Amersfoort, Keistad (boulder-city), originates in the Amersfoortse Kei, a 9-tonne (19,842 lb) boulder that was dragged from the Soest moors into the city in 1661 by 400 people because of a bet between two landowners. The people got their reward when the winner bought everyone beer and pretzels. Other nearby towns then nicknamed the people of Amersfoort Keientrekker (boulder-puller). This story embarrassed the inhabitants, and they buried the boulder in the city in 1672, but after it was found again in 1903 it was placed in a prominent spot as a monument. There are not many boulders in the Netherlands, so it can be regarded as an icon.
