Greece: Acropolis, Athens, and environs
Score: 53

"Substantial improvements in the past few years with interventions renovating public spaces, pedestrianization schemes, access via metro-underground, control of land uses in surrounding area."

"In serious trouble.The historical/architectural sites are no doubt amazing, but the 'wear and tear' on these places is noticeable and the throng of tourists at most times detracts from the experience.Also, from my observation, aside from the trickle down to opportunistic local establishments (e.g. overpriced and mediocre restaurants, aggressive vendors) near the Acropolis, the benefits are not felt by the locals."

"The city itself has improved and the air is much cleaner than 20 years ago. But much improvement needs to be done. It is not the friendliest city in the world, and most tourists after the obligatory two days at the sites look at getting to the islands. There is need for more greenery (pocket parks and so on)."

"Enhancement on other than Acropolis interpretation should be a priority, particularly in sites near Plaka.There is opportunity to engage visitors in the restoration, mitigation through volunteer tourism."

"Threatened by the corrosive effects of air pollution. The Acropolis and other sites have tremendous aesthetic appeal, and tourists are generally well-informed about the locale."

"The visitor numbers to the Acropolis are enormous. However, Athens has adjusted to the demand with surprising aplomb, and both the city and the site are admirably equipped to cater for these huge numbers."

Greece: Delphi and environs
Score: 73

"The environmental and built heritage integrity were just as good as 40 years ago! I hiked for miles around the valley, orchards, mountainsides and saw very little human degradation.The town of Delphi was remarkably similar though expanded in size with lots of accommodation choices.The backdrop for Delphi is remarkable—huge aesthetic appeal. The future looks good."

"Site well preserved, environs do not integrate well. Village is still too separate, too commercial with ticky-tacky activity. Still very special place, with all the spirituality of ancient Greece."

"The natural settings and human-made structures have great aesthetic appeal and are in good condition overall.Tourism development seems to benefit local people and motivate them to protect the locale.Development on the plateau above Delphi and ski resorts on Parnassus may be a threat.Prospects for sustainability are good."

Greece: Medieval city of Rhodes
Score: 63

"The impact of the hotel development adjacent to the medieval city is very negative. More and more shops selling tourist tat of the lowest order.The fabric of the buildings seems on the whole in good order.Lots of excavations opened up, but few people working in them."

"Admirably organized to deal with the enormous numbers of tourists that it receives each year.Facilities both for the mass tourists and for the more historically-oriented visitors. "

"Great numbers of tourists; many not oriented to heritage values."

"A once attractive destination subjugated to the interests and the priorities of mass tourism. An attractive place to find oneself only in off-season."

"Because of tourism pressure, it is losing its authenticity; souvenir vendors are taking over as much space as they can, residents seem to be absent from the old center or only coming there to support the tourism industry."
