Metsovo, village, Greece
Metsovo is a large town, with a substantial Vlach and Turkish influence.
Vlachs originated as a shepherding, nomadic culture. See www.vlachophiles.net/liddell. We found Vlachs in Romania, see Romania Road Ways;.
The picture here is a small mountain town heading from Metsovo to Ioannina. Roadsign: See a fine photo album at www.galenfrysinger.com/metsovo_greece. The area is highly traditional, old Turkish influence also there.
Then, at Ioannina, is the administrative capital of the region, there are palace-castle ruins, and Turkish homes now open as museums. There is a lovely mosque. See www.arafura.net.au/greeksnt/ioannina; and www.metsovo.gr/.
