Visit the festivities for the Dutch royal house on 26 April 18:00 till 27 April 18:00 in the city centre (dress code is bright orange).
Koningsdag or King's day is a national holiday in the Kingdom of the Netherlands. Celebrated on 27 April, the date marks the birth of King Willem-Alexander. When the Dutch monarch is female, the holiday is known as Koninginnedag ( ) or Queensday and, under Queen Beatrix until 2013, was celebrated on 30 April. She prolonged the tradition that was born under her mother's reign: Queen Juliana's birthday was on 30 April.
Domkerk
The Gothic Dom church (built between 1284 and 1520) is the major religious building in the city. It was a part of a larger cathedral which was partially destroyed by a severe storm while under construction. When a hurricane hit the town in 1674, the badly constructed nave collapsed, which is the reason that today the Domtoren (Bell Tower) and the church itself are separated by the Domplein (Dom Square). The interior of the church was stripped down of every sculpture during Reformation, but the exterior remains a lavishly decorated example of Dutch Gothic architecture. The 20th century stained glass windows are stunningly beautiful.
Dom Tower
112 m tall, it is the highest church tower in the Netherlands. It is also the highest building in the city by municipal mandate. Climbing up the stairs to see the magnificent view on the top is highly recommended, but beware of the narrow, steep stairs. On clear days you can look as far as Amsterdam and Rotterdam. Home to the second largest set of bells in Europe (after Cologne), and a carillon which is often played by musicians at the weekend.
Consecrated in 1048.
City Hall
It has a rather imposing look.
Perhaps it's the most famous bridge over the Oudegracht. It was created in 1547 by vaulting a space between the older two bridges: the Huidenbrug and the Broodbrug, thus creating one of the major squares in the old town.
It's another bridge over the Oudegracht which make a small square between Steenweg and Vismarkt. In the middle of the 16th century older 2 bridges – the Kalisbrug (or Visbrug) and Corduanierbrug – were connected together making the current Kalisbrug.
