The Rijksmuseum van Natuurlijke Historie (National Museum of Natural History) was a museum on the Rapenburg in Leiden, the Netherlands. It was founded in 1820 by Royal Decree from a merger of several existing collections. This happened on the initiative of Coenraad Jacob Temminck, who saw the museum primarily as a research institute for the University of Leiden. The total collection was already quite large at the time, and continued to grow from foreign expeditions and by obtaining private collections from inheritances. The location is currently used by the Rijksmuseum van Oudheden.

Leiden Law School is the law school, and one of the seven faculties, of Leiden University. Teaching and research in the school take place across campuses in Leiden and The Hague in the Netherlands. Instruction in law began with the university's founding in 1575. Alongside the disciplines of theology and medicine, it was considered a 'higher' faculty of great importance. It also established itself as the most international faculty due, originally, to the proportion of academics arriving from Germany in the mid-17th century. The law school has played a substantial role in wider Dutch society from its earliest years, being consulted in an official capacity on all manner of subjects from wills to piracy and privateering. The school's present form has its roots in the 1980s when a reformation of the division of legal disciplines took place. Sacrifices were made in the 'meta-legal' disciplines, e.g. jurisprudence and sociology of law, to focus on 'positive law', particularly civil and international law which are considered traditional fields of strength of the law school. The faculty completed its move into the refurbished Kamerlingh Onnes Building in Leiden in 2004 where it is housed to this day.Annually, the school has an intake of approximately 900 Bachelor's degree students and 1000 Master's and Advanced Master's degree students. Around 425 staff are employed in academic and administrative roles with approximately 325 in a teaching role. Approximately 18% of the academic staff are from outwith the Netherlands. The majority of school activity takes place in Leiden, the minority based in The Hague is chiefly within the Grotius Centre for International Legal Studies on the Campus The Hague.

The Leiden American Pilgrim Museum is a small museum in the Dutch city of Leiden dedicated to the Pilgrim Fathers (or simply Pilgrims). These Separatists or English Dissenters were religious refugees who had fled England to Amsterdam in 1608 and moved to Leiden the next year. They lived and worked in that city for about 12 to 20 years. In 1620, their emigration began. They left Leiden by canal, going to Delfshaven where they embarked on the Speedwell, which took them to Southampton. But the Speedwell proved leaky and had to be sold, so they transferred to the Mayflower. The Mayflower undertook the famous voyage to New England in 1620 alone. In the 19th century the colonists' first harvest festival after their arrival at Plymouth Colony was identified as the origin of the annual Thanksgiving celebration in the United States.
