She lived in the building with her parents, and after their passing, remained there alone until her death in 1958. Despite her reclusive lifestyle, she was a well-known and distinctive figure in the village.
After Koosje’s death, the municipality planned to demolish her house and the surrounding buildings. Thanks to local efforts, this was prevented. All houses were rebuilt under the supervision of Loenen-based architect Mr. Leicher. Around 40 years ago, after the reconstruction of Koosje’s house, the idea arose to open a restaurant in the building. At town hall, people referred to it as “the house of Aunt Koosje,” so charmed were they by the history of both the house and Koosje herself. This led to the decision to name the restaurant after her.
In its early years, the restaurant was a true bistro, with checkered tea towels as placemats and a menu filled with fish stews, onion soup, and braised dishes. Locals quickly found their way there — and that hasn’t changed! Today, Tante Koosje has grown into a fine dining restaurant known for its honest ingredients and excellent value for money.
