Mega Spilaio is a Greek Orthodox monastery in the municipality of Kalavryta, in the Peloponnese peninsula in southern Greece.
The monastery is located in a large cave in a sheer cliff, where the western slopes of Mount Chelmos drop down to the gorge of the Vouraikos river. The cave was known in antiquity, and the geographer Pausanias reports that the daughters of Proetus found refuge there during their madness. In the first Christian centuries, Christian hermits occupied the cave.
According to tradition, the monastery is one of the oldest in Greece, reputedly founded in 362 by the Thessalonian brothers Symeon and Theodore, who with the help of Euphrosyne (a local shepherdess, honoured as saint for her part in these events) discovered in the cave the icon of the Theotokos painted by Luke the Evangelist.
Its medieval history under Byzantine and Latin rule is obscure. The monastery gained prominence only from about 1354, when it served as the residence of the Orthodox Metropolitan of Patras, since the city was still occupied by the Latins and the seat of a Latin archbishopric. The complex suffered large-scale destructions in 849, 1400, and 1640, when it was comprehensively rebuilt.
Several of the monks became members of the Filiki Etaireia and took part in the Greek War of Independence. In 1934, the katholikon was destroyed in a fire, and replaced by a new church in 1937. On 8 December 1943, the German 117th Jäger Division destroyed the monastery and executed 22 monks and visitors as part of reprisals that culminated a few days later with the Massacre of Kalavryta.
The monastery was rebuilt from the ground after the war, and now comprises an eight-storey complex set in the 120 metres high cliff face.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
