There was no shortage of inspiration for the design of the garden. As a child, Rubens' wife Isabella had always had a large garden at her parents' house in the Kloosterstraat. And Rubens' Italian tours were also evident in the final design of his courtyard. In Italy, he discovered the most original city gardens in Genoa, as well as magnificent gardens in Mantua, Florence and Rome.
As a court painter, he was also privy to the expansive gardens of Archdukes Albert and Isabella at Coudenberg in Brussels. As such, the patch of greenery in the Rubenshuis was turned into a dazzling place to live. It was a green spot that Rubens loved and where, with all his curiosity, he had different varieties of local flora planted. Flowers, trees, bulbs, plants, animals and people. The garden belonged to everyone!
