Utrecht's cosy centre is like an open-air museum, and nearly every brick has a story to tell. The history of the city dates back to Roman times. But the Middle Ages also left their traces on the city. And you can see them everywhere. You're standing here on top of the border of the Roman Empire. And the countless houses, churches, monuments - and the characteristic wharves, of course - commemorate that rich history. And let's not forget the surroundings of Utrecht. It is surrounded by impressive citadels, forts and castles, including Kasteel de Haar, the largest castle in the Netherlands. Take a tour to the forts and hear the exciting stories of the Nieuwe Hollandse Waterlinie, or literally climb to the top of the Utrechtse Heuvelrug: the Pyramid of Austerlitz.
