Akershus Fortress
Akershus Fortress or Castle is a medieval castle that was built to protect Oslo, the capital of Norway. The first construction on the castle started around the late 1290s, by King Haakon V, replacing Tønsberg as one of the two most important Norwegian castles of the period (the other being Båhus). It was constructed in response to the Norwegian nobleman, Earl Alv Erlingsson of Sarpsborg’s earlier attack ...Bergenhus Fortress

Naveta d'Es Tudons
The Naveta d"Es Tudons is the most remarkable megalithic chamber tomb in the Balearic island of Menorca.
In Menorca and Majorca there are several dozen habitational and funerary naveta complexes, some of which similarly comprise two storeys. Navetas are chronologically pre-Talaiotic constructions.
The Naveta d"Es Tudons served as collective ossuary between 1200 and 750 BC. The lower chamber was for stashing the disarticulated bones of the dead after the flesh had been removed while the upper chamber was probably used for the drying of recently placed corpses. Radiocarbon dating of the bones found in the different funerary navetas in Menorca indicate a usage period between about 1130-820 BC, but the navetas like the Naveta d"Es Tudons are probably older.
The shape of the Naveta d"Es Tudons is that of a boat upside down, with the stern as its trapezoidal façade and the bow as its rounded apse. Its groundplan is an elongated semicircle. Externally, the edifice is 14.5 m long by 6.5 m wide and 4.55 m high but it would originally have been 6 m high.
The front, side walls and apse of the edifice consist of successive horizontal corbelled courses of huge rectangular or square limestone blocks dressed with a hammer and fitted together without mortar, with an all-round foundation course of blocks of even greater size laid on edge.
