List of twin buildings and structures

The term twin towers in architecture refers to two tall structures with nearly identical characteristics and similar height, usually constructed close to each other and part of a single complex. The charts below lists most twin and other multi-column structures with similar characteristics. Buildings and structures shorter than 100 m (330 ft) are not included.

The following list includes only twin buildings that are continuously habitable.

This list consists of nonbuilding structures. In other words, they are not continuously habitable. Masts and towers are considered structures.

Most strainers of HVDC Volgograd-Donbass are also twin structures. They consist of a single pole-type tower at which one conductor is fixed.

The following list shows the tallest completed twin buildings located in each continent:
