Town in Ireland realizes it would be too expensive to dig up its time capsule to celebrate the town's 200th anniversary

BBC:

"On 1 August 1821, the Marquess of Downshire was invited to place a time capsule in Donaghadee. It was placed and covered by a foundation stone"

...

[one of the men who built the town's lighthouse said] in his speech said that if this capsule was exposed some time in the future, the people of the town would realise how the harbour was actually built."
