Museum Het Leids Wevershuis consists of one of the last remaining "weavers' homes" (1560) in Leiden, Netherlands. The exterior, the large antique loom (1830) and the interior, are testimony of the once flourishing textile industry (and trade) around Leiden, in particular during the 16th and 17th century, when many home weavers supplied the draper's guild with high quality woolen cloth.

The Hooglandse Kerk is a Gothic church in Leiden. Its earliest parts date back to the last quarter of the fourteenth century. Most of the current structure dates from the fifteenth century. The brick church was dedicated to St. Pancras and today serves parishioners of the Protestant Church in the Netherlands.

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.

The Heilige Lodewijkkerk, also called the St. Louis Church, is a Roman Catholic church at the Steenschuur in Leiden.

The Leiden Weigh House (De Waag in Dutch) is a Rijksmonument located on Aalmarkt street (nr. 21). It was designed by Pieter Post around 1657 and opened in 1659. For centuries, merchants came here to weigh and trade a variety of goods. In addition to being a weigh house, the Leiden Weigh House has hosted a variety of engagements and stately celebrations over the centuries. Notably, Govert Bidloo converted an attic room into an autopsy room to study the human body.The weigh house was in use as an actual weigh house until 1972, when the last unit of cheese was sold. Nowadays, the building serves as a cultural monument, houses a bar and restaurant.

Zijlpoort is a city gate in Leiden, The Netherlands. The gate was built in 1667 in the classical style according to a design by the Leiden architect Willem van der Helm and with sculpture by Rombout Verhulst. Because the gates have to connect with the city wall as well as with a bridge, the building is in the form of a parallelogram. The Zijlpoort, together with the Morspoort (1669) and Doelenpoort (1645), are the only of the original eight gates that survived. The name refers to the nearby river, the Zijl. The predecessor of the Zijlpoort stood at the end of the Haarlemmerstraat that is now called the Havenplein. In the course of time, the Zijlpoort has, together with the hall above the passage, fulfilled different purposes over time: for example, at the beginning of the 18th century, a society of amateur poets and playwrights (a so-called guild of "rederijkers") was based there, and from 1736 there was a school for poor children. Afterwards in the late 19th century, the city had a storage room above the gate. In the last quarter of the 20th century, the Zijlpoort was renovated twice on a large scale. During the last renovation, in the 1990s, supporting constructions were put up on both sides of the gate. Since 1999, a catering shop has been established in one of them.

The Vrouwekerk ("Lady's Church") or Vrouwenkerk ("Ladies' Church"), originally known as the Onze-Lieve-Vrouwekerk ("Church of Our Lady"), was a 14th-Century church in the Dutch city of Leiden. In the early 17th Century, the church was attended by the Pilgrims (who left Leiden to settle in Plymouth Colony) as well as by the first colonists to settle on Manhattan.The ruined remains of this Gothic church are located on the Vrouwenkerkhof square opposite Museum Boerhaave, just north of the busy shopping street Haarlemmerstraat. The alley Vrouwenkerksteeg, which runs from the Haarlemmerstraat to the Vrouwenkerkhof, is also named after the Vrouwekerk church. The church remains have rijksmonument (national monument) status. In 2008-2009 the church underwent restoration. Carolus Clusius and Joseph Justus Scaliger were buried in the Vrouwekerk.

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.
