Trikorfa
Trikorfa is an order of peaks that stretches between the areas of Upon Chrepas and Sylimna. They lie west and above Tripoli, composing the gate of Mainaliou Pediou and of Central Mainalo. From here important roads are crossing, connecting (since antiquity) the Mantiniako Pedio with the Big Town, and Karytena, the medieval capital of Gortynia.
Arcadians are people of the mountains, also known for their rich mythology and civilization. They are also distinguished by their sense of freedom and their struggle for independence during the domination of the Ottomans. The fifty and more monuments, ancient, medieval and newer, (at the area of Sylimna) certify a historical and cultural route of more than 3.000 years.

        During antiquity Arcadians joined the other Greeks in battles against the Persian Empire and their bravery was distinguished in Thermopiles and Plataies. In Dipea, (near Mainalio Pedio and not far from Trikorfa), many Arcadians defended themselves from the powerful neighbor Sparta. Let us not forget that the Arcadians of the Achaikis Confederacy gave the final battle against the Romans. The medieval Mainalia Tavia, a unique town in Peloponese defends itself against the hordes of Mohamet II the "conqueror" (15th century AD).
After all these, it is not strange that at Mainalo the banners of freedom were again raised against the Turkish conquerors. First among the rebellious captens was Theodore Kolokotronis. It is not by chance that the strategic site of Trikorfa becomes the battle field of collision between the patriotic forces of the national revolution and the armies of the Ottomans

Tripolitsa during the Revolution of                             1821
            Tripolitsa with its benefitial geographical position was to become a major target of military operations. Theodoros Kolokotronis said: "In order to succeed we have to strike the enemy at his head" (meaning Tripolis). That war idea becomes acceptable to all and after a five months siege the city fell in Greek hands again. The victory of September the 23rd, 1821 constitutes the first important trophy of the revolution. Its political and military repercussions were enormous. In his "Hymn to Freedom", Dionysios Solomos dedicates parts of his poems to Tripolitsa. It must be also be mentioned that soon after the liberation of Tripolitsa the city revives its strong commercial activities .

       Since 1818 the "Filiki Eteria" (a revolutionary organization of that period) started to send there her apostles. This rebellious corporative movement spreads from Tripolitsa to other areas of Greece. Tripolitsa was the second (after Konstantinople and Moldavia), center of the "Filiki Eteria". From the 1.039 members of the organization 200 were Arcadians and between them 40 were from Tripolis. Among the latter are the Sekeri brothers and Panagiotis Arvalis. After the liberation and the epidemic of enteric fever that followed, Tripolitsa started its normal life anew. In February of 1822 Tripolis became the seat of Peloponesos' Senate. Unfortunately in June 1825 Imprahim took control of Tripolitsa using the city as the base of operations against other parts of Greece. In February the 16th, 1828, the Turkish guard abandons the city (after international pressure), burning everything down. For the next 5 days, the city is totally destroyed adding to a third disaster that followed those of 1770 and 1821.
But Tripolitsa came back from its ashes. In April fifteen locals built their new houses starting the formation of the new city. The street planning scheme of the town was ready since 1829 but was put into practice in 1836. The scheme's elaboration was made the engineer Stamatis Voulgaris (from Corfu) and the French captain Carnot. In 1829 a school of elementary knowledge was formed and expanded later in 1835 .
