Penella Castle is located about 7 km from Cocentaina in the province of Alicante, Spain. It was built in the 13th century, occupying the entirety of a limestone rock with vertical walls on its north side. The castle is named after the area where it is situated.
This castle belongs to the category of rural castles or fortified manor houses from the early Christian period. In 1271, King James I granted Ponç Guillem de Villafranca the villages of Peniella and Forminyàn, authorizing him to build a castle on the rock of Peniella.
Currently, the keep of the castle can be seen, with a square plan measuring 4 meters per side and 12 meters in height. The top of the keep is crenellated. Attached to the keep is a square-shaped building, which is also crenellated.
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.
