The functional use of the island has changed over the years, especially the 19th century brought many changes in infrastructure and the destiny of the island. When the economic and commercial significance of granaries and lead warehouses diminished (nota bene once imported by way of water from around Olkusz), rowing clubs found their place on the island, and recreation areas were also located here. At the same time, the municipal 15 sewage pumping station was built in the 1860s and 1870s with its characteristic chimney which has survived to this day.
At the end of the century of steam and electricity, the municipal power station stood on the Olowianka which after the Second World War was rebuilt into a combined heat and power plant.
After its closure, the buildings of the former power plant were transformed into the Baltic Philharmonic. Currently, after a thorough reconstruction, they form the Music and Congress Centre.
The western wharf, which can be admired from Motlava, was created in the present shape just a few years ago as a kilometer-long walking route.
The Olowianka can be reached via two bridges spread over the Stepka Canal or a drawbridge, connecting the banks of the Motława River.
