Moreover, visitors of the very famous nearby destinations like Vitina, Stemnitsa and Dimitsana can easily visit Piana.

At the revolution of 1821 the village played decisive role due to difficulties to access. For this reason the region around Piana constituted the ideal den for the Armatoloi and Kleftes.

In Piana were organised by Theodoros Kolokotronis the first military departments that strengthened the battle of Valtetsi and dominated over Turks in Tripolitsa later on. The name of Piana is historically unbreakably connected with the catering of Kolokotronis armed forces with the essentials for their winning battles.

In the courtyard of another beautiful church of the village, named Panagitsa Polykammeni, because of the repeatedly Turk's efforts to ruin it with fire, it is saved today a traditional wood-oven. By the ovens of Piana the Greek camps of revolution, were provided with bread .

In distance of 7 kilometres of westwards Piana is found the historical Limpovisi (Greek: Λιμποβίσι). It is the Homeland of Kolokotronis' Family and the natural space in which he grew during his childhood and also acted Theodoros Kolokotronis or Geros Tou Moria(Greek: Γέρος Του Μωριά). At the inventory of Enetoi(Greek: Ενετοί) in 1711 were recorded 500 residents at Limpovisi. Nowadays at Limpovisi, the House of Kolokotronis family has been restored and functions as a museum. In the courtyard of Limpovisi also exists the country church of Ai-Yannis(Greek: Άι-Γιάννης).

The wider space of Limpovisi was reformed with donation of the unforgettable Panagiotis Aggelopoulos in the year 1990. In the square functions also municipal refreshment stand.

In small distance from Limpovisi, is found the depopulated village Arkoudorevma (Greek: Αρκουδόρευμα). Arkoudorevma belonged to the community of Piana, and was abolished as a settlement in 1928. Deep in the gorge of Arkoudorevma, ruins of the old Arkoudorevma houses are saved until today.

The waters from the Arkoudorevma gorge meet with those of the Elissonas which crosses the plain of Piana.

Arkoudorevma is of equal historical importance with that of Limpovisi, because his embossed territory it constituted also this place suitable for reorganization of armed forces before the historical battles of 1821.

In the village functions the Folklore Museum of Piana with richly as much as unique exhibits.

The plain of Piana is crossed by the Elissonas River. The waters of Elissonas river gush from the sources of the foot of Pianovouni and it gives life to the very few residents of region that cultivate the ground or raise their animals. Important part of these sources' water of Elisson River is collected for the water supply of the residents of Tripolis, the Capital of the Arkadian prefecture.

In the middle of the plain of Piana, the waters of the Elisson river are lost deep in the ground and it is believed that they do appear again in the region of Megalopolis. At length dormitory of river Elisson used to function 12 stone watermills for the grinding of cereals of the region and 6 traditional stone washing factories (Greek: Νεροτριβή) for the washing of the heavy clothing. Some of these buildings are saved until our days in very good situation.

In the mountain that is found above the sources of Elisson river that called Pianovouni(Greek: Πιανοβούνι), is found the cave of the god Pan. The local fable, wants Pan to live in this cave and with his flute to flood with magic sounds the marvelous ravine of the Elisson Sources.

Traditionally Piana was very famous for the high production of apples and constituted very important income for the local economy. Particularly acquaintance was the cultivated variety Delicious Pilafa Tripoleos Apples (Greek: Μήλα Τριπόλεως). Today the cultivation of the apple trees has been minimized in total and just meets the needs of the Piana residents. The main causes that the culture of apple trees were abandoned, particularly the variety Pilafa Delicious, is related to the increased needs of trees in farming care as well as in not guaranteed and unstable output from year-to-year mainly due to the unfavourable meteorological conditions or the apple trees diseases.

Moreover, because a very important part of the ground of Piana as well as of the wider region, is covered with firs, it is produced honey of fir of high quality (Greek: Μέλι Ελάτης) as well as the acquaintance for the flavour of Honey of Fir Mainalou Vanilla(Greek: Μέλι Ελάτης Μαινάλου Βανίλια).
