The Tower of Piraeus, is an emblematic 23-floor building and the lighthouse of the port of Piraeus as well as the landmark of the city in general. After a year full of changes and challenges, our goal with this project was to give an extra festive vibe in the city and fill people with hope and positivity. We had the opportunity to collaborate with an amazing group of people and lighting experts in order to study, design and illuminate this historical building with the latest modern technology. We have presented a lighting installation full of colors and shapes, in order to create a ‘’festive urban jewel’’ highlighting the architecture and the importance of the building itself. Bringing together innovative technology and creativity, our main goal was to colour people’ s lives and enhancing a joyful and optimistic message.
