It is located in the Central Peloponessus in what is called Ορεινή Αρκαδία (Greek: Mountainous Arcadia) at a distance of 12 km west of Tripoli and an altitude of 1,050 m. It is a small plain terrain surrounded by four hills: Chomatovouni, Mylos, Katsikeika and Dovrouleika.
It soon became characterized by a strong common ethic code which was strictly guarded by the Valtetsiotes, who were renowned as warlike highlanders with an austere way of life and love for Greek tradition and Christian faith.
When it was not the Ottoman occupant's menace it was the strong winter which obliged shepherds to take their herds to milder weathers and pastures in the Argolid returning to Valtetsi in April.
The negative impacts of the Second World War and the Greek Civil War, which impoverished the region to an extent of very difficult subsistence, and the advent of modernization with the boom of urban life made younger generations to flee for new experiences at first towards nearby cities in the Argolid, second to Athens, Greece's capital city (notably in some of the neighbourhoods of Piraeus like Kastela or Palaio Faliro) and in the end overseas abroad to America being the United States, Canada and Argentina the three main places chosen as destinations.
The short distance within the village and Tripolis -which being the capital of the Ottoman vilayet of Morea became the main objective of the rebels- and the topographic characteristics of the place made Theodoros Kolokotronis to choose it as his stronghold prior to the final assault.
The Maniots, under the leadership of Kyriakoulis Mavromichalis and with the help of the local villagers, succeeded in fortifying the four hilltops by building small housetowers and installing defensive batteries.
[5] Prior to the Siege of Tripolitsa, Petros Mavromichalis, the commander-in-chief and bey of Mani arrived to the village with a strong army and camped at Valtetsi, establishing the Maniot seat of campaign and headquarters for the first time since the medieval period outside the limits of Laconia.
All the villages in the mountainous Arcadia and Valtetsi in particular were extremely loyal to the military party and their leaders such as the proper Kolokotronis, Nikitaras or the Mavromichaleoi against the civil party of Alexandros Mavrokordatos and the Aromanian blooded Kolettis, what made them to staunchly oppose the Bavarian regency as well as the Capodistrian government which they saw as undermining the local regional interests in behalf of centralization of power following Adamantios Korais' principles of a national, western, unitarian and homogenous state.
[6] The Second World War and the subsequent Axis occupation brought a desperate situation to Valtetsi due to the village economic dependence from the trading markets in the City of Tripolis.
Since most of the sheep and goats were confiscated by the Nazi occupants, the lack of food and the inflation made everyday life very difficult for the villagers because they could not manufacture the goods and products derived from these animals like milk, butter, cheese and furs.
