Heritage sites presenting the Story of Mann have opened for the 2006 season.
All Story of Mann attractions are open seven days a week
The story tells the Isle of Man's history through state-of-the-art displays including touch screens, model reconstructions and original artefacts.
It can be explored at 13 different sites around the island, starting at the Manx Museum in Douglas, which is open all year.
Other Manx National Heritage sites include Peel Castle and Castle Rushen, which is open until October.
Howard Parkin, Public Services Manager for Manx National Heritage, said: "It is a pleasure to once again reopen our heritage sites for the enjoyment of our many visitors.
"The Niarbyl Café and Visitor Centre, only opened at the end of last September, is our thirteenth Story of Mann site."
The new season will include a Manx May Day event and archaeological excavations at Rushen Abbey.
All Story of Mann attractions are open seven days a week from 1000 to 1700 BST, with the exception of the Manx Museum which is open Monday to Saturday.
