City Walk and Culture Utrecht

Start this tour by exploring the Dom Square and entering DOMunder, an underground discovery!

The entrance to the underground space where you can view 2,000 years of Dutch history is in the middle of Dom Square. A route under the centuries old square can be followed with a special torch to discover all sorts of archeological finds. History literally springs to life as the torch activates stories and animated films. DOMunder allows you to experience history from the time the Romans built the castellum Trajectum, around 45 A.D. and why Utrecht was the center of the Netherlands in the middle ages. You can even experience the destructive tornado that caused the nave of the Dom Cathedral to collapse in 1674.

Continue to explore the city on foot. There’s plenty to discover in the city centre of Utrecht. Turn into a random side street and you’ll forget for a moment that you’re in the middle of the city. You’ll find yourself suddenly in a hidden courtyard, a beautiful garden or a narrow alleyway with a special story. These are Utrecht’s forgotten places where time seems to have stood still.

Old Dutch; Castles and Windmills

Discover the surrounding area of the Utrecht city centre and visit a couple of ancient structures. We will start by visiting Slot Zuylen. Just outside of Utrecht city, situated along the river Vecht, lays the castle of Zuylen in the little village Oud-Zuilen. The history of the castle begins in the 13th century. The mediaeval castle was converted into a country house in 1752. In the 350 years before it became a museum, it was home to the family Van Tuyll van Serooskerken. When you visit Slot Zuylen it feels like you’ve landed in the 18th century and the family has gone out for the day. The collection consists of porcelain, glassware, paintings, furnishings and tapestries.

Afterwards we will proceed to visit the castle “de Haar” a medieval, moated fortress with towers and ramparts, gates and drawbridges. The castle was restored and partially rebuilt in the late 19th century and it rises like a real fairy-tale castle from a park with impressive trees, surrounded by gardens
and ponds. De Haar Castle is the biggest and most luxurious castle in The Netherlands. It is one of the top European historic houses. A visit to De Haar Castle will take you back to the glory days of the castle and will show you the breathtaking splendour that surrounded the international rich and famous in the early 20th century. De Haar Castle ranks among the top twenty most visited Dutch museums.

We will end the tour at De Ster (the star) sawmill, in Utrecht’s Lombok district, is the last fully-intact mill of its kind. It is a unique industrial monument and an iconic Dutch symbol right in the heart of the city. The sawmill was built in 1739 and was in use as a timber business for centuries. In 1991, wind power was replaced by electricity, and the windmill on the roof was demolished. When, in the 1980s, the sawing work permanently came to an end, new plans were made for the reconstruction of the mill. The surrounding 18th-century mill yard has largely remained intact and, together with the mill, is regularly the site of events such as festivals, open-air film screenings and concerts.

History of mathematics in the Netherlands: the city of Leiden

Leiden is a typical university city. Leiden University is the oldest university of the Netherlands, founded in 1575. Modern scientific medical research and teaching started in the early 18th century in Leiden with Boerhaave. On this excursion we will visit the museum that carries his name and also take a guided walking tour through the city centre, passing by locations with special significance for the history of mathematics.

Walking around Leiden, the city’s glorious history seems to come to life.  We will visit the Pieterskerk, were a replica of the gravestone of Ludolph van Ceulen shows his remarkable achievement of calculating the first 35 digits of pi, and the Begijnhof, were Count Maurits founded his school to train fortificationists and other engineers in 1600. Simon Stevin designed the math curriculum for this school. Van Ceulen and Frans Van Schooten Jr (known for his translation of Descartes) were teachers there.

The Times wrote: ‘Rijksmuseum Boerhaave is one of the most important scientific and medical history collections in the world’. As a national treasury of science, it puts five centuries of history on display regarding natural sciences and medicine. The emphasis lies on contributions from the Netherlands, including the microscopes made by Antonie van Leeuwenhoek, the oldest Dutch planetarium, and inventions by Christiaan Huygens.

Price per person: 50.
