Mobile lighthouse was designed to commemorate the 40th anniversary of the Paris port and to bring closer its activities to a broader audience. The design of the mobile lighthouse connects two basic port elements, a traditional lighthouse and containers. Lighthouses are one of most notable symbols of nautical transport and can be found in all traditional ports. Containers on the other hand are the symbol of the modern ports being one of the main transport elements, but also at the same time they are a perfect material to construct event architecture. They are accessible, they allow mobility and are easy to be constructed and re-set again on some other location. Four recycled 20-foot container are forming this 10 meters high Lighthouse. Top container has two rotating beam headlights, while the ground floor container hosts an information office/gallery promoting port activities in the Paris region and river transport as an alternative to road transport.
