It was conceived as a monument able to describe a helicoidal movement, yet the hefty maintenance costs (over 150,000 euros/year)[2] led to the Ayuntamiento de Madrid's preference for keeping it "static".

However, the complex network of tunnels that pass underneath the Plaza de Castilla made this original project unworkable, because of its weight.

In early October 2007, the Caja contracted construction company Acciona to carry out the project, and in July of the following year building work began, having dismantled the fountain which existed previously at the selected spot.

In fact, its design is inspired by the Endless Column, a work of 29.33 meters in height by Romanian sculptor Constantin Brâncuși, built in 1938 in Târgu Jiu, Romania.
