A “hofje” is a Dutch word for a courtyard with almshouses around it. They have existed since the Middle Ages. The Netherlands has several “hofjes”.

The Hofje van Aerden (or officially Hofje van Mevrouw van Aerden) was established at the end of the 18th century by Maria Ponderus, who wanted to provide free housing for impoverished female relatives from her or her husband's family. The stipulation was that these women had to prove their familial connection and adhere to strict behavioral and religious guidelines: remaining unmarried, of impeccable conduct, and of Protestant faith. Maria's vision was so profound that she ensured its continuation through a foundation established in her will, leading to the opening of the hofje on November 1, 1773.

The Hofje van Aerden was designed to house eleven women, but it expanded over the years. By the late 19th century, it could accommodate up to fifteen women. Today, the criteria for residency have evolved, and it now serves as a residence for ten single women.

The complex is arranged around a central courtyard, nearly square in shape, measuring approximately 40 by 32 meters. It was constructed on the site of the former Leerdam Castle, which was destroyed during the Eighty Years' War.
