Geopark Visitor Centers Signs Renewed With the logo change made by the UNESCO Global Geoparks Network, all geoparks affiliated with UNESCO started to use their new logos. Based on this, the panels at the entrances of the buildings where the Visitor Centers of the Kula-Salihli UNESCO Global Geopark are located were replaced with the new logo of UNESCO. The signs of both the Mudire Hanım Mansion in Salihli, the Virgin Mary Church in Kula and the Çakırca Visitor Center were replaced with signs with the new logo.
