Blaaktoren, Architectural structure in Rotterdam, Netherlands
The Blaaktoren is a residential tower in Rotterdam with stacked cubic volumes offset in a zigzag pattern that creates an unusual wedge-like silhouette. The structure rises across multiple stories, with each cubic residential unit featuring wide balconies and generous natural light penetrating the interior spaces.
The tower was completed in the late 1970s during Rotterdam's post-war reconstruction, when the city was reshaping areas damaged by earlier conflicts. Architect Piet Blom's project was part of an ambitious effort to bring modern residential living back into the urban landscape.
The tower represents the Netherlands' spirit of experimenting with new ways of living, and its stepped design creates visible variety in the city skyline. Residents use the numerous balconies and outdoor spaces, giving the structure an inhabited, lived-in character that changes with the seasons.
The structure sits in central Rotterdam with good access to public transport and is located in an active district with shops and restaurants nearby. Visitors can walk around the site freely and view the building from different angles to fully appreciate its unusual shape and construction.
The building is known by the nickname The Pencil because its shape resembles a giant pencil tip, which sets it apart from typical high-rises in striking fashion. This unexpected likeness to an everyday object makes the tower immediately recognizable and memorable to visitors.
