The Lutherse Kerk, also known as St. George's Chapel, is an 18th-century church in the Dutch city of Delft. The church's foundation was laid in the 15th or 16th centuries, with a wooden structure being built on top of it. This first wooden church burned down in 1536, and the city of Delft erected an armory where the church had stood. The armory was converted into the current Lutheran church in 1768, and a new stone facade and steeples where added to the existing building.

The Prinsenhof ("The Court of the Prince") in the city of Delft in the Netherlands is an urban palace built in the Middle Ages as a monastery. Later it served as a residence for William the Silent. William was assassinated in the Prinsenhof by Balthasar Gérard in 1584 - the holes in the wall made by the bullets at the main stairs are still visible. Since 1911, the building houses a municipal museum. Today, the building displays a collection of Dutch Golden Age paintings.

The Flower-holder (Tulpenvaas) is one of a matching pair of tulip vases dated to ca. 1690 and currently in the collection of Museum Het Prinsenhof.The pair was created in the tin-glazed delftware company called "De Griekse A" ("The Greek A") in Delft. A flower-holder such as these was meant to maximize the use of tulips and each tubular hole in the top was meant for one individual flower, as tulips were so expensive at the time. Each vase can hold 15 tulips. It is unusual to see tulip vases in pairs. This pair is unusual both for its age and condition, and was purchased by the museum in 1975 after the vases were put on display by Aronson Antiquairs of Amsterdam at an art fair hosted by the museum itself. Each vase was made in four separate pieces. The assembly consists of a foot-piece, a vase that rest on it, and a double-layered lid with tubular holes. These tubular holes are referred to as spouts, but were not used for pouring. The lids fit into each other and were designed to hold 8 and 7 individual blooms respectively. The Greek A factory was known for its decorative table objects, but also became known for its extravagant tower vases, that held many more flowers. These tower vases would have been very costly to have filled completely. Tulips were very difficult to propagate and were considered quite expensive, though no longer as expensive as they had been during tulip mania when speculation in the market for flower bulbs caused several well-to-do growers to go bankrupt in the 1630s. It is unknown who designed this specific pair of vases, but a similar vase in the collection of the Metropolitan Museum of Art without the foot piece was designed by Daniel Marot for the Greek A factory during the period of Adrianus Koecks, who is documented working there during the years 1689–94.A replica of a tulip pyramid vase made by De Griekse A in this period was used as a backdrop for President Obama's visit to the Netherlands in 2014. Each tier of the vase containing spouts is a separate piece. While the paired vases have two tiers, pyramid vases can have 10 or more tiers of spouts.

The Saint Hippolytus Chapel (Dutch: Sint-Hippolytuskapel) is a chapel in the old city of Delft. It is one of the oldest buildings in Delft, and since 1967 it has been designated the Rijksmonument.The church was built around 1400 in the Gothic style and is located on the east side of the Oude Deft. Until the Reformation, the Oude Kerk was consecrated to Saint Hippolytus, and the name of the chapel comes from the city quarter. At the time of foundation, it was a part of the already existent female religious community, similar to a monastery - Holy Spirit Sisters House (Dutch: Heilige Geestzusterhuis). It was built on the foundations of the older chapel and was consecrated in 1412. In 1536, it was badly damaged by a fire and subsequently restored. In 1572, during the Reformation, the interior of the chapel was emptied, and the clock and the cross were taken from the tower. After 1581, it was used as a depot, but a part of the chapel was still used for service by Protestants.In 1910, the chapel was restored, and the design of the facade was altered, making it to look more like the original design. Since 1924 and until the construction of the new campus of Delft University of Technology in 1966, the doctorate ceremonies of the university were held in the chapel. In 1972, it was transferred to the Roman Catholic Church and since 30 July 1972 is used for service.

The Mensenvereniging Wolbodo was founded in 1959 as the PSK (Parochiele Studenten Kring) by 17 students, who were Catholic, but did not want to join the Catholic student society Virgiel. In 1960 the name was changed to Sanctus Wolbodo or in Dutch "Sint Wolbodo", referring both to the saint who supposedly is the patron saint of students and to its Catholic nature.
