The story that haunts this land
Your mission begins at the Philips Museum, Emmasingel 31, 5611 AZ Eindhoven. It was here that Gerard Philips founded his first light bulb factory in 1891, laying the groundwork for the technological empire that would transform Eindhoven into a center of innovation. The museum documents this central role, and it is from this official starting point that the 'Philips' Secret Plan' journey begins. Here you collect your first clues, crucial to understanding the stakes of the Dutch Resistance in 1944.
The route then leads you to Stadhuisplein, Eindhoven's central square, a major urban crossroads. This key stage of urban games is integrated into the 'Outside Escape' circuit for a narrative puzzle. You decipher hidden messages on the facades, revealing the initial contacts between Philips management and Resistance networks. It is on this square that the outlines of the secret plan are drawn, designed to protect the vital workers and infrastructure of the city of Noord-Brabant.
Your investigation leads you in front of the Lichttoren, the Light Tower, a symbolic monument of the Philips legacy. This tower represents the city's founding lighting industry and is integrated into the 'Philips' Secret Plan' themed circuits. By exploring its architecture, you discover how Philips' technological innovation could have been diverted to serve the cause of the Resistance. The shadows and lights of this building hide secrets of ingenuity and bravery at the heart of Eindhoven.
The statue of Frits Philips, a central figure in the Resistance and Eindhoven's industrial history, is an unmissable stop. This monument, integrated into the 'Eindhoven — Philips' Secret Plan' routes, symbolizes the link between Philips' innovation and the bravery of the Dutch in 1944. At its feet, you perceive the scale of sacrifice and determination of those who, like Frits Philips, worked for freedom in Noord-Brabant. The Ketelhuis, a historic Philips building in Strijp-S, a former Philips industrial district transformed into a creative and cultural space, is also an important site from this period.
Your quest concludes at 18 Septemberplein, Eindhoven's commemorative square, linked to the Liberation and the Dutch Resistance. After passing the Sint-Catharinakerk, a Gothic church mentioned as the endpoint of many routes, you arrive at this square. Here, the final elements of Philips' secret plan are revealed, paying tribute to the audacity and resilience of a city that managed to rise again. This self-guided urban game will have allowed you to walk in the footsteps of history, from Eindhoven's design innovation to the memory of the 1944 Resistance.
