This list ranks the tallest buildings in the European Union that stand at least 100 metres (328 ft) tall, based on standard height measurement. This means that spires and other architectural details are included in the official height, but not antenna masts, as it is defined by the Council on Tall Buildings and Urban Habitat. Only habitable buildings are ranked, which excludes radio masts and towers, observation towers, cathedrals, steeples, chimneys and other tall architectural structures. Since 2011, the tallest building in the EU has been The Shard in London, United Kingdom, at 310 metres (1,017 feet).
This list includes buildings under construction that have already been topped out. Architectural height is considered, so masts and other elements added after completion of building are not considered.
Some skyscraper enthusiasts prefer this measurement, claiming that the extensions that can or cannot be deemed "architectural" are subjective. However, many non-architectural extensions (such as radio antennas) are easily added and removed from tall buildings without significantly changing the style and design of the building, which is seen as a significant part of the value of these buildings.
The list includes all skyscrapers of at least 200 metres (656 ft) tall. However the height data is subject to fluctuations due to simple changing of mast extensions. This list includes buildings under construction that have already been topped out.
This lists buildings that are under construction in European Union and are planned to rise at least 110 metres (361 ft).Approved or proposed buildings are not included in the table. Included are renders of the finished towers or images of the current construction sites.
The following is a timeline of the tallest buildings in the European Union (EU) and its direct predecessor, the European Economic Community (EEC) established in 1957.
