This is the Royal ship Wasa, that sunk in Stockholm in 1633 I believe. It was salvaged about 30 years ago and has been conserved and restored. It has its own museum in Stockholm. If I´m correct, then about 75% of the ship is in original. The rest has been made new. You can read more about it here http://www.vasamuseet.se/en/. It´s in english.
