These ruins belong to a hotel at Mandraki village, at Kerkini Lake in Greece.
Hotel was originaly built very close to the lake but some years later, as the level of the water rose, owners had to abandon original building for a newer one. Old hotel was left as it is in the picture for some decades.
Now those ruins do not exist anymore as of Spring 2005. Water slowly destroyed buinding’s foundation.
This picture was shot in November 2003.
