Work on the New Church, or Nieuwe Kerk, which stands in the Market Square opposite City Hall, began in 1381 and the tower was completed in 1496. With subsequent rebuilding and expansion the church was only finally finished in 1655. The tower is the second highest in the country at 356 feet. There is a very steep and narrow staircase you can climb that leads to a platform offering spectacular views over the city and the surrounding countryside. The mausoleum of William I, Prince of Orange lies within and in the private crypt the kings and queens of the Netherlands are buried, along with other members of the House of Orange.
The viewing platform is on the next level above the clock face and and is a great spot for taking photographs of the city.
Delft makes a wonderful day trip from Amsterdam. Travel time by train is around one hour and trains stopping in or connecting to the city leave Amsterdam Centraal every 10-15 minutes. If time is short another option is to combine Delft with a visit to Den Haag which is only a fifteen minute train journey from Delft.
