As asked on the European Castles post for any omission, I created a new request :
Andorra : Castell de Sant Vicenç d'Enclar
is a medieval castle located near the village of Santa Coloma in Andorra. It dates back to the 9th century and served as a strategic defensive stronghold. Today, it is a well-preserved archaeological site and a popular tourist attraction.
Canary Islands : Castillo de San Jose
was built in-between 1776 and 1779. It was commissioned by King Carlos III of Spain to serve as a coastal defense fortress against pirate attacks. The castle's strategic location on a hill provided clear views of the coastline, enabling surveillance and protection of the area.
Faroe Islands : Skansin fortress
was originally built in 1580 by Magnus Heinason, a Faroese naval hero, to protect against pirate attacks. Over the centuries, it underwent several expansions and modifications. Skansin played a significant role in defending the Faroe Islands during various conflicts, including battles against English privateers and other naval threats.
Iceland : Borgarvirki Fortress
is a volcanic plug in North Iceland that historically has been used as a fortress. It stands at 177 metres above sea-level, and 10 to 15 metres above its surroundings. Made of volcanic strata in a columnar shape, it is little wonder why early Vikings saw that it was a perfect place to utilise as a fortress. As such, Borgarvirki has not just been a natural feature for hundreds of years; it has been added to with walls, stairs and other amendments to further fortify it and make it habitable for humans. Two ruins of human habitations are on site, and there is a freshwater well within it.
Kazahkstan : Turkestan City Fortress
, Turkestan was founded in the year 490 by nomadic settlers. The cultures on the Eurasian Steppe would transform Turkestan, allowing it to prosper into the modern age. From a time when city walls and fortifications protected a powerful city to protecting traditions, cuisine, and spirituality.
Monaco : Prince's Palace of Monaco
, built in 1191 as a Genoese fortress, during its long and often dramatic history it has been bombarded and besieged by many foreign powers. Since the end of the 13th century, it has been the stronghold and home of the Grimaldi family who first captured it in 1297.
Russia : Novgorod Kremlin
or Detinets, as it was called in Novgorod in old times, is the most ancient out of the preserved Kremlins in Russia (it was first mentioned in the chronicle of 1044). It was founded by Prince Vladimir, the eldest son of Yaroslav the Wise.
