The Abdij, the abbey complex
Founded in the twelfth century by Norbertine monks and grown into a walled complex of three churches, five towers and a set of gates. The two-year siege of Middelburg in 1572 to 1574 ended monastic life here by force, and the buildings passed to the province, which still governs from them. Walking into the abbey courtyard is free.
The courtyard is the quietest corner of the centre and the best place to start, because everything else radiates from it.
