In 1590 Clusius founded the Hortus botanicus Leiden. 425 years later it is time for a celebration! The garden turns 425 in 2015, making it the oldest of The Netherlands, and second oldest in the world! This occasion should be celebrated with as many people as possible. DoubleMatured designed a classical ‘Clusius’, which can be used by the gardens for various communication purposes. Using a number of key items from the collection, they also created a festive illustration. Visitors can use a handy museum guide to experience the gardens through the ages.
