Construction of the Mary Rose Trust's new purpose-built museum at an advanced stage of construction ahead of it's official opening in late 2012. It will house the Tudor warship that was built in 1511 close to the spot where she now lies. Mary Rose was one of the first warships to carry heavy guns. She famously foundered during an engagement with a French invasion fleet in 1545 as King Henry VIII looked on from Southsea Castle. She was raised in 1982 and has been undergoing conservation work at Portsmouth Historic Dockyard since that time.
