Yes, it is family-friendly. Children can enjoy exploring the abbey courtyard and the adventure of climbing Lange Jan.
The Middelburg Abbey complex, including the 'Old Middelburg Cathedral' remnants and the Nieuwe Kerk, is generally family-friendly. The large, open courtyard provides space for children to move around, and the historic atmosphere can be engaging. For older children and active parents, climbing the Lange Jan tower can be an exciting adventure, offering impressive views and a sense of accomplishment.
However, note that the climb up Lange Jan involves many stairs and is not suitable for very young children or those with mobility issues. Inside the church, quiet behavior is expected. Stroller access might be limited in certain historical sections or during specific events, but the main abbey grounds are easily navigable.
