Impact of emblematic projects

Emblematic projects have a significant impact on culture and society. They can help revitalise a city, promote a new artistic movement or simply inspire people to appreciate architecture.

The Burj Khalifa contributed to Dubai’s transformation into an international business and tourism centre. Beijing’s National Stadium was a symbol of globalisation and innovation during the 2008 Olympic Games. 30 St Mary Axe inspired other architects to design more sustainable and efficient buildings. The Metropolitan Opera House has contributed to enriching New York’s cultural life. The Agbar Tower contributed to the renewal of Barcelona’s harbour area.


Architecture isn’t just construction, it’s art, it’s history and it’s legacy. The emblematic architectural projects we’ve explored are perfect examples of how creativity and innovation can transform the environment and leave an indelible mark over time. For architects in training or in practice, these works are inexhaustible sources of inspiration and learning.
