Balti Station
The spheres glowing low around Balti Station, where Kalamaja meets the Old Town, could be buoys washed ashore. Buoy is an outdoor globe light, set into the planting beds when the station grounds were rebuilt as part of Tallinn's Vana-Kalamaja reconstruction. After dark they light the walk at a soft, pedestrian level, marking the route rather than floodlighting it.
