Nieuw-Herlaar Castle is on the east bank of the Dommel, about a hundred meters from the hamlet Halder, to which it is connected by a bridge.

Haanwijk Manor is not a true castle, but it has the medieval tower 't Vaantje on the estate grounds.

There are multiple pictures of the 17th and 18th-century situation, showing that it was indeed a true castle with a square layout with an inner court surrounded by a moat.

Such a structure would be in line with the repeated use of the castle in the Eighty Years' War but should be confirmed by research.

In 2008 an archaeological excavation at the castle grounds uncovered walls of 1.3 m thick in a brick size corresponding to the late 14th century.

The right to appoint a priest in the chapel on the courtyard was retained by the Lord of (Oud) Herlaer.

[2] Willem van der Aa Florisson transferred Nieuw-Herlaer to Jan die Joede for two ground rents, one of 100 Electoral Rhine guilders, and one of 100 Rhine guilders for him and his nephew Goyart van der Aa Gerritszn at Zegenwerp.

After not paying the ground rent Jan die Joede transferred Nieuw-Herlaer to Anthony van Glymes in 1447.

The couple then transferred Nieuw-Herlaer to Hendrik van der Aa Gerritsz., who was registered as lord on 7 August 1449.

Margriet would get a usufruct on Nieuw-Herlaer, which was transferred to her sister Cornelia wife of Jan van Renesse.

[4] Gerard Proening van Deventer, son of Jacob and Barabara Bax Johannesdaughter was a Calvinist and played a big role in the early stages of the Eighty Years' War.

In November 1579 Claude de Berlaymont made Nieuw-Herlaer his headquarters for a few months,[5] and had a garrison of soldiers from the 's-Hertogenbosch militia.

[7] In 1586 the city militia garrisons in many places surrounding 's-Hertogenbosch, including Nieuw-Herlaer, were commanded by Captain Bontenos van der Sterre.

In June 1587 the Dutch army arrived before Loon op Zand Castle and took it after a week's siege.

It next moved forward to the southeast, and on 1 July 1587, the Royalist garrisons of Nieuw-Herlaer and Nemerlaer Castle retreated.

[9] During the late sixteenth century the watermill of Halder, which was within sight of the castle, was very important for fulling wool cloth.

It meant that inhabitants of the Meierij which paid contribution to the Dutch Republic could exercise this important economic activity at Halder without getting plundered.

[11] For Nieuw-Herlaer Castle the final stage of the Eighty Years' War was the conquest of 's-Hertogenbosch by the Dutch army in 1629.

When Bishop Michael Ophovius had to leave 's-Hertogenbosch after it changed sides in 1629, he was kindly received at Nieuw-Herlaer.

During the first phases of the Eighty Years' War, the castle became the property of Maria and Anna Proening van Deventer, who had both become Catholic again.

Maria would bring her half to the family Van den Broeck / Pybes d'Adema and successors.

Her daughter Maria van den Broeck brought this half of the estate to Reynier Pybes d'Adema (?–1671).

His nephew Joseph Wolfgang Endevoets, cadet in the Dutch army and Lord of Zwanenburg next succeeded.

Adolf and Adriana's younger sister Maria married Dirk Millinck van Gerwen.

It was then described as: 'Half of a noble castle with multiple rooms, with a chapel, a house and a brewery with kettle and cask.

[17] It was bought by Colonel Onno Tamminga, baron du Tour, who lived at Haanwijk Manor.

He passed it on to Philip Willem baron de Schmeling, who was succeeded by the Prussian general Constantijn van Billerbeck.

In 1911 came the French Benedictine sisters from Jouarre Abbey, fleeing the secularization policy in France.

[21] In 1955 most of the building was bought by the College van Regenten over de Godshuizen en den Algemeenen Armenzorg in 's-Hertogenbosch.

In the late 1980s, Myrke Stalman and Chiel van der Linden managed the castle.
