Mercedarian monastery of San Juan de Poio was built in the 17th century and reflects the taste for combining Classicist and Baroque styles. The first document of the monastery on the site is however much older, dating from 942 AD.
Inside, there is a splendid retable from the 18th century, in Churrigueresque style, and the tomb of St. Trahamunda is in the left-hand aisle (much venerated in the district). The procession cloister (16th century) is also noteworthy, with a Baroque fountain and an original stairway. Also worth mentioning are the library, the museum of mosaics, the Escola de Canteiros or the centre for the Summer University courses. The monastery is currently devoted to tourist accommodation, governed by the nuns.
References: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.
