It was gifted to Workington's Curwen family in in 1568 by Mary Queen of Scots and the 'The Luck of Workington', a communion cup, has now returned to the town.
The Luck, which still belongs to the family, has not been in the town for 40 years is now on public display in a specially designed and lit secure cabinet at the Helena Thompson Museum.
The cup is thought to have been Mary's travelling communion cup. A spokesperson from the Museum said:
"The museum is just over the road from Workington Hall, where Mary stayed during her last night of freedom.
"Its return will (hopefully) bring what Mary wished for more than 400 years ago - 'luck to Workington.'
"Once she gifted it away, her luck nose-dived. A Roman Catholic and thought to be a threat to the Protestant English Crown, she was arrested eight months after her one-night stay in Workington (May 15 1568),- and then detained under guard for more than 18 years. Her death warrant was signed by Elizabeth 1 and her execution (by beheading) took place at Fotheringay Castle on February 8, 1587."
