What will Barcelona look like in a 150 years?
In commemoration of the 150th anniversary of Barcelona city's urban development,
all city residents had the chance to answer this question.
The answers are contained in a time capsule, which will be opened in 2159.
The capsule formally evokes the icon of the campaign’s graphic image by combining symmetry and reflection.
The passage of time is marked with an encoded message that will make sense as its opening approaches.
The sculpture will remain protected by Barcelona's Science Musem CosmoCaixa until 2159.
