In the post-war period, the site (located in a privileged place, with an excellent view of the ancient lagoon and bay) was in danger of disappearing, a victim of real estate speculation. However, efforts by those in favor of its preservation, most notably the Swedish archaeologist Solveig Nordström, succeeded in defending the site. This effort culminated in the 1961 designation as an "Artistic and Historic Monument", which afforded some legal protection. Unfortunately, the preservation movement could not stop much development around the site, with the result that the ruins are surrounded by tall buildings and is in no way "visually pure".
