A different kind of visit
If you are looking for a local history museum, consult the current information from Museum Sint Paulushofje. The Heemhuis is mainly of interest if you want to look something up specifically or learn more about local history. That calls for different expectations from an ordinary museum tour.
Consulting the documentation
In the Heemhuis you can consult library and documentation material and buy local history books. Bring a specific question and ask in advance whether suitable material is available. That way your visit can better match your research or personal interest.
Keeping the locations apart
The Heemhuis is on the Burchtplein. Het Groene Hoekje on the Bisschopsmolenstraat is a different place with its own hours. Old museum listings on the Markt do not belong to a current museum schedule under the name Jan uten Houte.
Before you go
Check whether you need the Heemhuis, Het Groene Hoekje or Museum Sint Paulushofje; they are different visiting options.
