A Roman cavalry helmet sold for £2.2m after it was discovered in a Cumbrian field is to go on show in Carlisle from Friday.
The Crosby Garrett Helmet, named after the village near Penrith where it was found using a metal detector, will be displayed at Tullie House Museum.
Museum director Hilary Wade said it was "one of the most extraordinary objects from the Roman period in Britain".
Tullie House attempted to buy the helmet when it was auctioned in 2010.
It was bought by a private bidder.
Its display at Tullie House is supported by the Art Fund and The Monument Trust.
Ms Wade said: "It was made for splendid sporting events rather than battle and shows what a spectacular impression the cavalry would have made.
"The helmet will complement our Roman collections and will add to visitors' appreciation of the Roman presence in this region."
Following its stint at Tullie House, which runs until 26 January, the helmet will go on show at the British Museum.
