Even it is not something the human race should be proud of, we think that there should be mentioned as well monuments that were destroyed, but there are some evidence that can make us imagine them. Except the lost areas of Vryssaki and Rizokastro, here is a list of them.
Frankish tower of Acropolis
Areopagus is clear today, but during Mycenean and prehistoric times there was a cemetary there. There were moden settlements as well, built down during the ancient Agora excavations (as with Vryssaki area). There were more buildings as a cistern during Hellenistic times, houses during Roman and Byzantine times, but in 1962 excavations a church was discovered, that was mentioned to Pope Innocent III Bull of 1208. It was a larger church thn that of Monastiraki that someone can visit today. The church of Saint Dionysius Areopagus was dated around 7th century. There were found also some tombs around the area.
During Early Christian years, Athens’ Bishop Leonidas was a martyr (during Emperor Decius at 250 AD) as most of the early Christians. He was honoured at Illisos Vasilika, built somewhere around 5th century, probably with the aid of Athenian Empress Eudokia. The temple was destroyed and its ruins were embeded in Haseki’s Wall phase, at 1778. Remains can be found on site, but also at Athens Byzantine Museum.
