Justinian’s work of the late 6th century. A.D. cruciform inscribed temple after dome. It was researched in the 1930s by Professor Orlando. It was partially restored, cleaned and studied in 1965 by the archaeologist Chariklia Barla. It is the best-preserved early Christian monument in Central Greece and one of the most important monuments of this period in the entire Greek area. Located in the Lilea-Polydrosso region, in the northern valleys of the Fokida, one is still able to find the most abundant springs of the Kifissos river.
Close to the Aghia Eleousa spring in Polydrosso, the Lileans created an area of worship where they would worship the god of the river and would bring great offerings with them. Preserved in the area are the foundations and architectural parts of the ancient drinking fountain and an imposing retaining wall that supported the temple that was dedicated to the river. In the early Byzantine period, these buildings of worship were replaced by the churches of Aghios Christoforos and Aghia Eleousa, which were constricted using much of the ancient building materials. Today, these springs comprise of one of the most beautiful tranquil and relaxing locations in Delphi.
