The Monastery of Prousos (Monastery of Panagia Prousiotissa = Virgin Mary of Prousos) is built in beautiful surroundings on a steep rock and above the deep canyon of the river Karpenisiotis. According to the tradition, it was founded in 829 by monks Dionysios and Timotheos, who brought with them the icon of Virgin Mary from Prousa in Asia Minor. However, it is more possible that the monastery was established between the 12th and 14th century.

The monastery has a main building where Virgin Mary Prousiotissa is worshiped and a part where the cells of ther monks are located. A small museum is housed in the monastery with several exhibits such as icons dating back to the 15th and 16th century, sacred vestments, silver and golden chalices and handwritten codes and typography books.

During the War of Independence against the Turks, it was a refuge for Greek rebels. In August 1944 German troops burnt down a large part of the monastery, destroying many relics, handscripts, books and items of everyday use. The monastery has been rebuilt several times.
