Zagreb, developed along the Sava river, has a rich history dating from the Roman period. Sava river divides the city into North and South parts, connected by some bridges. However, people lack the true experience of connection between the two parts of the city apart from the transportation connection. It needs an urban design and architectural proposal to create a sense of connection through the visual experience and common activities and events. The proposed site of the tower is the heart of Zagreb where Sava river changes its path creating a curved barrier between North and South. The shape of the tower takes the inspiration of this striking curved form of the river to reflect the flow of time from past to present to future. The tower as a hyperbolic paraboloid ring offers circular and vertical movements as a continuous staircase having an additional four sets of curved escalators. This continuous stair symbolizes the endless movement on the tower offering ‘infinite’ viewpoints to the visitors, allowing to look over the whole city, the old and new landmarks of the city, and reminding the rich history of the city and inspiring for the prospect of the future.
