Above the left bank of the river Lousios, at the base of a tall and wild rock and almost opposite the Philosophos Monastery, dominates the historic monastery of Timios Prodromos. It was built in the 16th century and is today one of the largest and most historic monasteries in the Peloponnese. It is a male monastery and has more monks than the other monasteries of Arcadia. Its tradition dates back to the middle of the 12th century (1167).
The frescoes, despite the damage, are remarkable and, according to Fotis Kontoglou, date back to the 16th century and belong to the Cretan School. In fact, the Cretan and Moscow are considered to belong to Theophanes. The monastery has a remarkable library with important theological and philosophical books. There are old photographs, ecclesiastical faces and letters of Kolokotroni in the Prefecture of Igoumenion and Archontariki.
The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
