The previously dreary pedestrian subway under the freeway by the GAMMA building is now decorated by an original mosaic by Jan Lukeš, created as part of the Shards of Joy (Střepy radosti) project. Around 50,000 hand-cut tile pieces were used for the mosaic with motifs of the undersea and terrestrial worlds, which made this site more colourful and far more cheerful. The actual implementation lasted more than 10 months. PASSERINVEST GROUP, the developer of this complex, invested 550 000 crowns in the overall modifications to the pedestrian subway, including the new lighting.
Pedestrian subways tend to be unsightly and some people are even afraid to walk through them alone. Until recently the pedestrian subway leading to the Kačerov metro station or to Budějovická Street was one of these. Thanks to the mosaic, this space has been transformed into a work of art, which will make the daily trip home or to work more pleasant for everyone who passes through. An underwater world with various types of fish is on one side of the subway, and the terrestrial world with all the beauties of nature on the other side. Both of the seemingly opposite worlds are joined by the colour blue, representing water and air, supported by the element of bubbles. Works by Jan Lukeš, primarily known thanks to the Free Mozaik project, can be seen more and more frequently on the streets of Prague. The mosaics on Chorvatská Street in Prague 10 or the playground in Heroldovy Sady are worth mentioning.
The reconstruction of the pedestrian subway under the freeway is another of the public-interest activities by PASSERINVEST GROUP, which invested more than 100 million crowns this year (without any subsidies) in the public space of Prague 4. In BB Centrum it built a new pedestrian overpass, it opened an athletic stadium for the public and it created a new public space, Brumlovka Square, with an interesting fountain and water jets, which are surrounded by families with children in the summer months.
