The Nieuwe Kerk (New Church), formerly the church of St. Ursula (14th century), is the burial place of the princes of Orange. In 1584, William the Silent was entombed here in a mausoleum designed by Hendrick and Pieter de Keyser. Since then members of the House of Orange-Nassau have been entombed in the royal crypt. The latest are Queen Juliana and her husband Prince Bernhard in 2004. The private royal family crypt is not open to the public. The church tower is the second highest in the Netherlands, after the Domtoren in Utrecht.
The Nieuwe Kerk is remarkable for its fine tower and chime of bells, and contains the splendid allegorical monument of William the Silent, executed by Hendrik de Keyser and his son Pieter about 1621, and the tomb of Hugo Grotius, born in Delft in 1583, whose statue, erected in 1886, stands in the market-place outside the church. The tower was built 1396-1496 by Jacob van der Borch, who also built the Dom in Utrecht during the years 1444-1475. The monument for Hugo de Groot was made in 1781. The mechanical clock has 18 bells by Francois Hemony from 1659 and 30 modern bells. In the church tower there is a bell from 1662 made by Francois Hemony.
References:Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
