Kasteel de Pierpont

Kasteel de Pierpont is a late-classicist manor house from the early 19th century in Herk-de-Stad, Belgium, set within a historic park known for its unusual collection of trees. Despite the word "kasteel" (castle) in its name, the building was never a fortified stronghold — it started life as a private residence and now houses part of the town's municipal administration.

Who built the manor house?

The building was constructed in 1813 on the initiative of Joannes Godgaaf Hermans (1772–1856), a local tree nursery grower. Hermans didn't just build a home — he laid out the surrounding park himself and gave it the name "Eendracht" (Concord). His professional background in dendrology shaped the estate: he filled the grounds with exotic tree species grafted onto native rootstock, a horticultural approach that was unusual for the region at the time.

Where does the name "de Pierpont" come from?

Hermans had no children of his own, so he named a distant relative, Adèle van de Hove, as his heir. When she married François de Pierpont, the entire estate — house, park and all — passed into the hands of the de Pierpont family. It's their name, not the family that actually founded the estate, that stuck to the property through the generations that followed.

What happened to the estate in the 20th century?

The de Pierpont family remained connected to Herk-de-Stad until around 1960, when the last of them left for France. After their departure, the domain was looked after by a local association, the Olmenhof committee, which managed the grounds during the transitional years before public ownership.

The municipality of Herk-de-Stad bought the castle and its park shortly before the administrative merger with Schulen-Berbroek, which took effect on 1 January 1977. The purchase and subsequent restoration were driven by then-mayor Sylvain Minten together with alderman Henri Knuts and councillor Eugène Thiery. That timely intervention kept the estate from falling into disrepair, unlike a number of comparable properties in the wider region.

What is the building used for today?

Following its restoration, the manor house was adapted for administrative use: part of Kasteel de Pierpont now functions as offices for Herk-de-Stad's town hall. Rather than leaving a heritage building empty, the municipality chose to give it a practical second life while preserving both the structure and the character of the surrounding park.

What's worth seeing on site?

Beyond the building itself, the park is the main draw — many of the trees planted during Hermans' lifetime are still standing. The collection of exotic species grafted onto local rootstock remains a rarity for the area and stands as a lasting record of the original owner's horticultural passion, dating back roughly two centuries. Walking through the grounds traces the site's full arc: from a private botanical project, to a family residence, to today's municipal offices.
