Gebouw Delftse Poort (Gate of Delft Building) is an office complex consisting of two skyscrapers located on Weena 505 next to the Rotterdam Centraal railway station in Rotterdam. The taller tower's (Until May 2009, the highest office in The Netherlands) height is 151 metres 41 floors and the shorter tower's height is 93 metres 25 floors. Both towers are built over a 4-storey multifunctional podium which adjoins the Rotterdam central station. The entire complex has 28 elevators. The gross floor area in the complex is 106,000 square metres and the offices occupy 66,000 sq m.
It was constructed between 1989 and 1992. The cost of the construction is 240,000,000 Guilders, or about US$130,000,000. Due to a metro tunnel running underneath the complex, advanced construction methods were required, allowing only a single underground floor to be built. Since the main user of the building is a Dutch Company called 'Nationale Nederlanden' (National Netherlands) the building is also known as 'Nationale Nederlanden building'. Nationale Nederlanden is the local insurance branch of ING Insurance.
Until 2004, a race up the building's stairs was organised.
