Over the summer Ammannati's statue of Neptune had his hand repaired. You may recall that a drunk accidentally tore it off while trying to climb the massive statue last year. The fountain is also running, which it wasn't for all of last year, and large planters have been placed inside the steel railing that surrounds the whole thing to further thwart the over zealous from trying to wade in the fountain or climb the sculptures. The planters have also been strategically placed to keep people off the steps of the Palazzo Vecchio.
The restoration cost €11,000 - the city is trying to raise an additional 1.5 million Euros to completely restore the fountain.
