Delftse Poort
Delftse Poort: architecture and business beside Rotterdam Centraal
Delftse Poort is one of the most recognisable office buildings in central Rotterdam. Located beside Rotterdam Centraal and Weena, it was for many years one of the great symbols of the city’s vertical growth.
The complex was designed by Dutch architect Abe Bonnema and opened in 1991. It consists of two rectangular towers of different heights connected by a shared base.
The main tower rises approximately 151 metres and has 41 floors, while the second tower is around 93 metres high and has 25 floors. Between 1991 and 2005, Delftse Poort was the tallest building in the Netherlands.

The origin of the name Delftse Poort
The building takes its name from the historic Delftse Poort, one of the gateways to the old city of Rotterdam.
The gate once stood near this area and formed part of the city’s fortifications for centuries. Although it disappeared as Rotterdam changed and expanded, its name lives on in several places and buildings in the surrounding area.
The modern skyscraper therefore connects the contemporary business architecture of Weena with part of the history of old Rotterdam.
History of Delftse Poort
The development of the building is closely connected with Nationale-Nederlanden. In 1963, Nationale Levensverzekerings-Bank of Rotterdam and De Nederlanden van 1845 of The Hague merged to form the new insurance company.
As the company grew, so did the need for a large office headquarters in Rotterdam. Land was acquired beside Weena and Stationsplein, in an area that was rapidly developing into the city’s new business district.
In 1986, a restricted architectural competition was organised and Abe Bonnema’s proposal was eventually selected. His design was based on two towers that could operate relatively independently.

Architecture of Delftse Poort
The architecture of Delftse Poort reflects Rotterdam’s business development during the 1980s and 1990s.
The two towers have a restrained geometric design, with glass and stone façades and a strong vertical structure. The difference in height prevents the complex from appearing completely symmetrical and helps create an easily recognisable silhouette.
Its location beside Rotterdam Centraal meant that for decades it was one of the first elements of the city’s skyline seen by travellers arriving in Rotterdam.
From corporate headquarters to multifunctional building
For many years, Delftse Poort was closely associated with Nationale-Nederlanden and functioned primarily as a corporate office complex.
From 2015 onwards, the complex was renovated to make it more open and flexible. New spaces for meetings, restaurants, working and other activities were introduced, following the trend of transforming large office buildings into more accessible and multifunctional places.
Today, Delftse Poort remains one of the most prominent business buildings on Weena and a characteristic feature of central Rotterdam’s skyline.
