This is shown on the basement level, where the north façade east of the bridge is 20 cm backwards.

[2] After the conflict with Joanna, Duchess of Brabant a new section of 12.50 of 5.82 m was added on the east side, probably shortly after 1400.

The large outer bailey was closed by a free standing gate building with the year 1536.

[8] In 1269 the Manor and Lordship Venloon (later known as Loon op Zand) were granted to Willem II of Horne (c 1230-1301) by John I, Duke of Brabant.

Next came Willem IV of Horne (1302-1343) married to Oda van Putten en Strijen (1295-bef.1336).

Loon op Zand was inherited by Johanna of Horne (?-1356), who married Gijsbrecht III of Abcoude.

Their son Sweder of Abcoude (c. 1340-1400), sold Loon op Zand to Pauwels van Haastrecht.

[9] On 29 August 1383 Joanna, Duchess of Brabant granted the Lordship of Loon op Zand to Pauwels van Haastrecht schout of 's-Hertogenbosch after he had paid Sweder of Abcoude.

Next came Willem, who had a son named Pauwels van Haastrecht, lord of Loon op Zand, Tilburg, Goirle and Drunen.

This Pauwels married Catharina of Naaldwijk and had a son Dierick van Haestrecht (?-1492), who became Lord of Loon op Zand on 26 August 1473.

[11] Dierick and Philiberta were probably responsible for large building activities on the outer bailey.

Floris was dead by 1559, and so Cornelia married Caspar van der Lip Lord of Blijenbeek and Afferden.

Loon op Zand Castle became part of a front line that covered 's-Hertogenbosch, and in 1579 it got a garrison from that city.

[14] On 24 June 1587 the Dutch army under Philip of Hohenlohe-Neuenstein moved through the Langstraat, and bombarded Loon op Zand castle with 5 guns.

Here he beat Claude de Berlaymont, and founded Fort Crèvecoeur to block communication between 's-Hertogenbosch and the Meuse.

[16] On 30 July 1587 the Dutch garrison set the castle on fire and retreated,[14] but in all probability the keep was still standing afterwards.

[8] Peter Ernst I von Mansfeld-Vorderort now re-occupied Loon op Zand Castle for the Spanish side.

On the vulnerable east and north side, it now get an earthen wall or rampart to protect it from cannon fire.

[14] In September 1587 the city of 's-Hertogenbosch requested Alexander Farnese, Duke of Parma to occupy Loon op Zand Castle, the Sconce of Engelen, and other places with the soldiers that were in pay of the city and Meierij van 's-Hertogenbosch, instead of occupying these places with soldiers which were not paid.

The Lords of Loon op Zand allowed Catholics to attend mass in the castle chapel.

[8] Ferdinand of Immerseel (?-1696), son of Thomas and Madeleine succeed to Loon op Zand in 1677.

Prince Louis Charles Otto of Salm-Salm (?-1778) descendant of Engelbrecht's sister Maria got Loon op Zand.

[19] From 1777 Louis Charles started a reconstruction of the castle, so it would look like a modern (i.e. eighteenth century) manor.

[19] In 1857 Sophia de Roy van Zuidewijn, widow of Franciscus Xaverus Verheijen bought the castle.

The final Vereyen on the castle was freule Emily Verheyen, who lived there 1942-1984 and married a Ten Horn, a physician.

He was antiques dealer, who used the main building for his business and organized modern art exhibitions on the castle grounds.

He wanted to do a radical reconstruction, and threatened to let the castle decay if the municipality of Loon op Zand would not cooperate.

The radical plans were not approved by the Rijksdienst voor het Cultureel Erfgoed, and also led to an occupation of the castle by angry inhabitants, and threats to squat it.

[20] De Pundert then agreed with some locals that he would give them the castle for free if they would found a foundation with a charitable status.

Next the Stichting (foundation) Het Witte Kasteel was founded to preserve the castle and to give it a useful purpose.
