 Although the restorers said at the time that the monument would withstand a hundred years without another major restoration, it was discovered a few years later that the gilding of the stars was damaged, due to the restoration technique used.The stars were restored again during maintenance and restoration in 2006; however, this restoration was rushed and there is no warranty of its quality.As of 2016 the monument is regularly monitored and its lower part is cleaned and covered with a protective coating every five years.
