Vimianzo Castle construction began in the 13th century and was completed during the 14th and 15th centuries. It is in an excellent state of preservation. Its walls are surrounded by a moat over which a drawbridge is lowered. The building was constructed in a polygonal design with four towers and an arms courtyard. Its walls, almost two metres thick, withstood numerous attacks during the Irmandiñas (Brotherhoods) Wars. It was the object of fierce disputes between the Archbishop of Compostela and the Moscoso family, two of the greatest powers in Medieval Galicia.
For centuries it was the residence of the Counts of Altamira, until it was sold to the Martelo family. Finally it was passed into the hands of the A Coruña Provincial Government, which restored it and put it to public use.
In its interior we can visit a very interesting ethnographic museum, which contains examples of the craft specialities of the region, from stonework to baskets, as well as lace, ceramics, clogs and linen items, amongst others.
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.
