Gripenberg Castle (Gripenbergs slott) is a wooden manor house. It is considered to be the biggest wooden castle in Sweden and one of the oldest that remain today as well.
The castle was built in 1663 as a huntig seat for the field marshal Carl Gustaf Wrangel. Its architect is unknown, but there is some reason to believe, that it might have been Nicodemus Tessin the Elder. It is assumed that the castle's name is derived from the name of Wrangel's mother Margareta Grip and that Wrangel might have chosen it to commemorate her. By the end of the 17th century the castle was bought by Samuel von Söderling and remained in the possession of his family until today.References:
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.
