After about twenty minutes drive we arrive at Andritsainna, a traditional historic village built amphitheatrically on the slopes of Lykaion at an altitude of about 750 meters. It is a town that was developed during the Frankish period (12th – 13th century AD) and refers to the Chronicle of Morea. Andritsainna played an important role in both the Orlof (1770) and the Greek Revolution (1821). In 1826, the city was destroyed by the troops of Ibrahim. Today, the village still has its mansions, paved alleys and its square with tall trees. Trani Vrissi, (big water source) located right across from it, is the oldest of the Peloponnese and was built in 1724. In Andritsaina there is the famous Nicopolopoulos Library, founded in 1840, with rare manuscripts of the 16th and 17th centuries, rare books in Greek and foreign languages, important documents from the period of the revolution and rich folklore material. Today, the collection of the library numbers over 40,000 volumes of books.
