# List of tallest buildings in Cardiff

This is a list of the tallest buildings in Cardiff that are 45 metres (148 feet) in height and above in the capital of Wales. They include buildings ranging from the ornate civic centre to the historic Cardiff Castle and Llandaff Cathedral.
The city's growth is reflected in its growing skyline. As is the case with many British cities, some of Cardiff's skyline comprises 1960s and 1970s residential and commercial tower blocks. However, current development trends for high-rise buildings include upmarket apartments and office space.
Cardiff is the largest city in Wales and has the most tall buildings in the country. Designed by Rio Architects, the tallest building in Cardiff is Bridge Street Exchange at 85 m (279 ft). It replaced Capital Tower in 2018, which, at 80 m (260 ft), which had been the tallest building in Cardiff since 1970.
Cardiff Council considers a tall building within the city centre and Cardiff Bay to be 8 storeys or more or from 25 m (82 ft) in height. Any proposals to the council for a tall building should "Generally be located within an existing cluster or form part of a proposal to create a new cluster (a cluster can be defined as a group of buildings which form a visual cohesion from more than one viewing point)".
