Leiden is about a 20 minute train ride north from The Hague.
The city is known for its university, the birthplace of Rembrandt in 1606 and for its beautiful, old city centre (the second biggest after Amsterdam).
Legend has it that as a reward for defending Leiden against Spanish attacks, the residents of the city were given the choice between not paying taxes for a period of time, or, the founding of a university.
The residents chose the university.
The University of Leiden is the oldest in the Netherlands and dates back to 1575.
