Emergency services have been battling to save historic sites on the outskirts of Athens as wildfires cause further devastation in coastal resorts.
While there has been a slight easing in weather conditions, hundreds of Greek and foreign fire fighters are still straining to contain blazes on the eastern outskirts of the capital, which have already led to hundreds of homes being evacuated and the loss of some 15,000 hectares of pine forests.
Anger is also growing over the lack of preparedness by the authorities exactly two years after the start of similar wildfires that killed 77 people.
So far casualties have been averted this year, but more than a dozen homes have been gutted and scores more are feared lost.
'The fires are continuing but with less intensity than in the previous days,' fire service spokesman Yiannis Kapakis said.
More than 500 fire fighters have been involved in the effort to douse the fire around Athens, bolstered by counterparts from France, Italy, Austria, Cyprus and Turkey.
Crews on the ground have been backed up by water-bombers.
The fires have threatened some of Greece's most important archaeological sites including the ancient Athenian fortress of Rhamnous, near Grammatiko, where firefighters again battled to hold back the flames.
The plain of Marathon, site of the battle in 490BC between the ancient Greeks and invading Persians, was also engulfed in smoke over the night.
Elsewhere, fire crews managed to save the Pantokrator Monastery, which was founded in the mid-14th century, from being burned down after the nuns occupying it refused to evacuate.
News also emerged of other fires bringing havoc to some of the country's tourist retreats, including the Ionian resort island of Zante and Skyros, an island in the Aegean Sea.
The fire started late Friday in a rural area of Grammatiko, 40km northeast of Athens, where a new waste disposal facility strongly opposed by residents is to be built.
