The powder cellars on the north shore are part of the Vallisaari fortress. Now the space of Ruutikellari has been renovated and it is possible to rent it as a gallery space or even for a private wine tasting. The maximum capacity of the space is 40 people at a time.
The basement has natural humidity and is always a relatively cool space. The room has dehumidifiers in use.
