In the 1960s, the Bolivian government initiated an effort to restore the site and reconstruct part of it. The walls of the Kalasasaya are almost all reconstructed. The original stones making up the Kalasasaya would have resembled a more "Stonehenge"-like style, spaced evenly apart and standing straight up. The reconstruction was not sufficiently based on research; for instance, a new wall was built around Kalasasaya. The reconstruction does not have as high quality of stonework as was present in Tiwanaku. As noted, the Gateway of the Sun, now in the Kalasasaya, is believed to have been moved from its original location.
