The outer bailey, with its five gates with brick pilasters and stone capitals is seventeenth century.

Their son Albert Francis van der Voort married Maria Pollart in 1685.

[3] Henry Albert Barthold of Dongelberghe (?-1727) had married Catharina Maria van Eyck (?-1753).

[4] She inherited Blaarthem Castle from her father, and brought it into her marriage to Van Dongelberghe.

[5] In 1753 Francis Hyacinth became formal owner of some lands which had previously belonged to Philip Charles.

The Comtes de Pas became lords of Kasteel Well in the late seventeenth century.

[6] Willem Liedel, son of a Prussian petty official became a ship doctor.

The big renovation of the castle is dated to the year 1763, formed by the anchor plates in a wall.

His widow then made Knight Willem de Liedel heir to the lordship of Well and Aldendriel, and died two months later.

He would gain some favor with king Louis Bonaparte of Holland and Emperor Napoleon.

Their children Willem Lodewijk Jan Baptist (1799-1849) and Sophia Francisca Antonia (1801-1816) were already dead when Pierre Guillaume de Liedel died on 2 December 1852.

Her son Franz Seraphin Peter Freiherr von Schlossnigg became the next lord of Well and Aldendriel.

A Ms. Marianne Evers van Aldendriel (1804-1878) kept the usufruct of Pierre Guillaume's estate.

[12] The reason is that Pierre Guillaume de Liedel had an affair with Eleonore Philippine von Schloissnigg (1780-1851), the younger sister of his wife.

The affair led to the birth of Marianne von Evers van Aldendriel.

Of course she could not become lady of Well, but her father provided for her by giving her the usufruct of his estate till her death.

[13] She was probably the mother of Willem and Marianne der Nederlanden, who are assumed to be illegitimate children of William II of the Netherlands.

In 1906 a Roman Catholic boarding school for boys was established in some of the rooms of Aldendriel Castle.

Jacob Adriaan's daughter Marijke Oudenaarde married dentist Jochem Oerlemans, and the couple lived on the castle grounds.
