Η ιστορική Δημητσάνα, χτισμένη πάνω στην αρχαία Τεύθιδα, οικισμός διατηρητέος και γεμάτος μνήμες, ιστορία και μύθους,χτισμένη πάνω σε δυο αντικριστούς λόφους, πάνω από το φαράγγι του Λούσιου ποταμού.
Η Δημητσάνα αποτελεί ένα πραγματικό θρύλο για την ιστορία της Πελοποννήσου και για την προσφορά της στο έθνος κατά την επανάσταση του 1821.
Σε όλη την περίοδο της Ελληνικής Επανάστασης, η Δημητσάνα
αποτέλεσε το σημαντικότερο κέντρο ανεφοδιασμού σε μπαρούτι. Μάλιστα ο Θεόδωρος Κολοκοτρώνης έγραψε γι αυτό: "Μπαρούτι είχαμε, έκαμνε η Δημητσάνα. Του μπαρουτιού την υπόθεση την είχαν πάρει απάνου τους τ'αδέλφια Σπηλιωτόπουλοι και δια να δουλεύουν το μπαρούτι επαίρναμε Δημητζανίτες στο στρατόπεδο".
Στους 14 μπαρουτόμυλους της κατασκευάζονταν όλο το μπαρούτι της επανάστασης.
Για το λόγο αυτό η Δημητσάνα ονομάστηκε «μπαρουταποθήκη του Έθνους». It is built on the west slopes of Mt Mainalon, at an altitude of 1.000 meters, over the river Lousios Gorge. Some of the most important accounts of Tefthis can be found in the writings of the great traveler and geographer Pausanias, who visited the town in 174 AC and included this visit in his “Arcadian” writings. Archaeological findings in the area confirm that Tefthis was a large walled city with an acropolis that grew to its full strength mainly in the classical and hellenistic years. The name “Dimitsana” is much more recent, possibly of Slav origin, and linked to the arrival of Slav groups in Peloponnese between the 7th and the 9th century. The earliest mention of the name is found in a manuscript of 967 concerning the Philosophos Monastery. From the 16th century on, Dimitsana experienced rapid growth (Concealed School- Philosophos Monastery School and Dimitsana College). From these faculties graduated innumerable scholars, priests and schoolteachers. At the same time crafts, manufacturing and trade were also on the rise (floor and water mills and tanneries). In the Revolution of 1821, Dimitsana played a key role as ammunition supplier with its gunpowder mills working night and day in order to supply the Greek front. After the war and the Constitution of the Greek State, Dimitsana enjoyed its status as the financial and trading centre of the region. In the beginning of the 20th century the population reached a peak of 2500 and it was only after 1950 that this figure started to fall as a result of immigration. Dimitsana has been characterized as a ‘traditional settlement” protected by the Ministry of Culture. This factor as well as careful investment activity from locals has made it one of the most popular destinations since the 1980s. Photo by John Adamopoulos for DeepGreece.com
