As "New Meppel Cathedral" does not exist, family friendliness cannot be assessed. The Grote Kerk in Meppel is generally family-friendly for quiet visits.
Since "New Meppel Cathedral" is not a real place, its family-friendliness cannot be evaluated. If the question refers to the Grote Kerk in Meppel, assumptions can be made based on typical church visits.
The Grote Kerk in Meppel is generally family-friendly, particularly for older children who can appreciate historical architecture and maintain a respectful demeanor. For very young children, an extended visit might be challenging as it is a place of worship and quiet contemplation. There are usually no specific child-focused activities or facilities within the church itself. However, the surrounding market square (Markt) often hosts events or has cafes that are suitable for families before or after a brief visit to the church. It is important to guide children to be respectful of the environment, especially during service hours, if they are simply visiting for sightseeing.
