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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
