About Leiden

Leiden is easily one of the most enchanting cities in the Netherlands. It's home to the oldest university in the country, the birthplace of Rembrandt and breeding ground for ground-breaking science and Nobel laureates for centuries. It's a charmingly compact fortified city, packed with well-preserved historic heritage but with a young and lively atmosphere due to its large student population.
