Castles & Gardens of Europe celebrates what makes Europe’s castles, palaces, and gardens so captivating. We’re building a platform—including a print magazine—that inspires people worldwide to discover these extraordinary places. Through partnerships with castle museums, luxury brands, and historic venues, we’re creating something that benefits everyone: shining a spotlight on Europe’s architectural treasures while delivering real value to our partners and readers.
What we offer partners
Castle and palace museums, luxury hotels, and premium brands get access to an audience that genuinely cares about culture and heritage. Our aim is to publish a collector’s edition magazine, together with a digital presence, to provide focused exposure through advertising, advertorials, and distribution across Europe’s most iconic heritage sites. Partners gain visibility, potential revenue from magazine sales, and association with a brand that shares their values—all while helping celebrate our European heritage.
How it started
Sander Louis, a musicologist and entrepreneur who runs Green World Media, founded Castles & Gardens of Europe out of his genuine passion for European culture, history, and historic gardens. In the Netherlands, he volunteers at Amerongen Castle and Zuylestein’s historic walled garden. In 2020, he launched Kastelen & Tuinen Magazine as editor-in-chief and publisher. In 2025, he served on the jury for the VriendenLoterij Kasteelprijs, which recognizes the most beautiful and best-managed castle garden in the Netherlands.
Now he’s thinking bigger: a pan-European magazine and platform celebrating the continent’s castles, palaces, and historic gardens. The vision is a beautifully crafted collector’s edition available in museum castles and palaces across Europe, distributed through airports, hotels, and cruise lines—helping international visitors discover these remarkable heritage sites. Using the approach that worked in the Netherlands, the magazine supports heritage institutions by bringing them to a wider audience while letting them share in the revenue. It’s about cultural preservation that actually pays for itself.
