Power Tower was a one-hour performance, designed for Urban Festival 10, and taking place simultaneously in the streets of Upper Town and the Tower of Lotrscak in Zagreb, Croatia.

In Power Tower, the artist completed a walk in Upper Town based on a pre-determined route. The route covered an area of Upper Town that existed in the Middle Ages and that was taken by many former residents on a daily basis. This route is also where most of today’s administrative buildings of Zagreb and Croatia are located, and as such is heavilly controlled by CCTV. While walking this route, the artist avoided the unwanted control imposed by CCTV, for instance by walking under or behind the cameras, on the opposite side of the street, etc. At the same time, the audience locateded in the Tower of Lotrscak warned the artist – through the ringing of a bell – when they saw a human threat approaching. This function was similar to the way the Tower was used in the Middle Ages when a group of watchers observed through a telescope the dangers surrounding Upper Town and warned the residents against them through the ringing of the tower bell.

Once the artist heard the warning, she immediately switched the tracking function on her phone making herself visible to the audience (as a moving object on a map), as well as walked towards and in front of the CCTV, making herself visible to them, too.
